The PF driver spams the system log with messages about VF VSI when VFs are created, as well as each time they are reset. This is annoying, and the information isn't even useful most of the time. Remove this message to reduce user annoyance. Change-ID: I8de90d05380f54b038c9c8c3265150be87c9242c Signed-off-by:

Move the IRQ tracking setup and teardown into the same routines that do the IRQ setup and teardown. This keeps like activities together and allows us to track exactly the number of vectors reserved from the OS, which may be fewer than are available from the HW.

For future device support we do not want to map the whole CSR space since some of it is mapped by other drivers with different mapping methods. Note: As a side effect, the flash region (if exposed through the memory map) gets unmapped too since it follows the future use region.

Some FW versions are incorrectly reporting a breakout cable as PHY type 0x3 when it should be 0x16 (I40E_PHY_TYPE_10GBASE_SFPP_CU). If we get this value back from FW and the version is < 4.40, reassign it to I40E_PHY_TYPE_10GBASE_SFPP_CU. Change-ID: Ibb41a0e3cd2c0753744e8553959240df6ed13ae8 Signed-off-by:

During resets (possibly caused by a Tx hang) the driver would accidentally clear the XPS mask for all queues back to 0. This caused higher CPU utilization and had some other performance impacts for transmit tests. Change-ID: I95f112432c9e643a153eaa31cd28cdcbfdd01831 Signed-off-by:

0x2A is the NVM version so it has useful data but it is per image version every image can have a different one. 0x18 is the dev starter version which all the images for release will have the same version. Of the two 0x18 is more useful and is what should be displayed. Change-ID: Idf493da13a42ab211e2de0bef287f5de51033cca Signed-off-by:

In CEE mode the firmware does not set the operational status bit of the application TLV status as returned from the "Get CEE DCBX Oper Cfg" AQ command. This occurs whenever a DCBX configuration is changed. This is a workaround to remove the check for the operational and sync bits of the application TLV status till a firmware fix is provided.

1. Use c_index and ring->c_index to determine how many TxCBs/TxBDs are ready for cleanup - c_index = the current value of TDMA_CONS_INDEX - TDMA_CONS_INDEX is HW-incremented and auto-wraparound (0x0-0xFFFF) - ring->c_index = __bcmgenet_tx_reclaim() cleaned up to this point on the previous invocation 2. Add bcmgenet_tx_ring->clean_ptr - index of the next TxCB to be cleaned - incremented as TxCBs/TxBDs are processed - value always in range [ring->cb_ptr, ring->end_ptr] 3. Fix incrementing of dev->stats.tx_packets - should be incremented only when tx_cb_ptr->skb != NULL These changes simplify __bcmgenet_tx_reclaim(). Furthermore, Tx ring size can now be any value. With the old code, Tx ring size had to be a power-of-2: num_tx_bds = ring->size; c_index &= (num_tx_bds - 1); last_c_index &= (num_tx_bds - 1); Signed-off-by:Petri Gynther <pgynther@google.com> Reviewed-by:

Alexander Duyck says: ==================== ipv4/fib_trie: Cleanups to prepare for introduction of key vector This patch series is meant to mostly just clean up the fib_trie to prepare it for the introduction of the key_vector. As such there are a number of minor clean-ups such as reformatting the tnode to match the format once the key vector is introduced, some optimizations to drop the need for a leaf parent pointer, and some changes to remove duplication of effort such as the 2 look-ups that were essentially being done per node insertion. v2: Added code to cleanup idx >> n->bits and explain unsigned long logic Added code to prevent allocation when tnode size is larger than size_t ==================== Signed-off-by: -

This change updates the fib_table_lookup function so that it is in sync with the fib_find_node function in terms of the explanation for the index check based on the bits value. I have also updated it from doing a mask to just doing a compare as I have found that seems to provide more options to the compiler as I have seen it turn this into a shift of the value and test under some circumstances. In addition I addressed one minor issue in which we kept computing the key ^ n->key when checking the fib aliases. I pulled the xor out of the loop in order to reduce the number of memory reads in the lookup. As a result we should save a couple cycles since the xor is only done once much earlier in the lookup.

The fib_table was wrapped in several places with an rcu_read_lock/rcu_read_unlock however after looking over the code I found several spots where the tables were being accessed as just standard pointers without any protections. This change fixes that so that all of the proper protections are in place when accessing the table to take RCU replacement or removal of the table into account. Signed-off-by:

If we are going to compact the leaf and tnode we first need to make sure the fields are all in the same place. In that regard I am moving the leaf pointer which represents the fib_alias hash list to occupy what is currently the first key_vector pointer. Signed-off-by:

This change makes it so that the insert and delete functions make use of the tnode pointer returned in the fib_find_node call. By doing this we will not have to rely on the parent pointer in the leaf which will be going away soon. Signed-off-by:

This change makes it so that the parent pointer is returned by reference in fib_find_node. By doing this I can use it to find the parent node when I am performing an insertion and I don't have to look for it again in fib_insert_node. Signed-off-by:

This change makes it so that leaf_walk_rcu takes a tnode and a key instead of the trie and a leaf. The main idea behind this is to avoid using the leaf parent pointer as that can have additional overhead in the future as I am trying to reduce the size of a leaf down to 16 bytes on 64b systems and 12b on 32b systems.

Alexander Duyck authored
This change makes it so that we only call resize on the tnodes, instead of from each of the leaves. By doing this we can significantly reduce the amount of time spent resizing as we can update all of the leaves in the tnode first before we make any determinations about resizing. As a result we can simply free the tnode in the case that all of the leaves from a given tnode are flushed instead of resizing with each leaf removed. Signed-off-by:

Sathya Perla says: ==================== be2net: patch set Hi Dave, the following patch set includes three feature additions relating to SR-IOV to be2net. Patch 1 avoid creating a non-RSS default RXQ when FW allows it. This prevents wasting one RXQ for each VF. Patch 2 adds support for evenly distributing all queue & filter resources across VFs. The FW informs the driver as to which resources are distributable. Patch 3 implements the sriov_configure PCI method to allow runtime enablement of VFs via sysfs. Pls consider applying this patch-set to the net-next tree. Thanks! ==================== Signed-off-by: -

This patch implements the .sriov_configure() PCI method to allow for runtime enabling/disabling of VFs. The module param "num_vfs" is now deprecated. At the time of driver load the PF-pool resources are allocated to the PF. When the user enables VFs, the resources are then re-distributed across PFs and VFs based on the number of VFs enabled.

When SR-IOV is enabled in the adapter, the FW distributes resources evenly across the PF and it's VFs. This is currently done only for some resources. This patch adds support for a new cmd that queries the FW for the list of resources for which the distribution is allowed and distributes them accordingly. Signed-off-by:

On BE2, BE3 and Skhawk-R chips one non-RSS (called "default") RXQ was needed to receive non-IP traffic. Some FW versions now export a capability called IFACE_FLAGS_DEFQ_RSS where this requirement doesn't hold. On such FWs the driver now does not create the non-RSS default queue. This prevents wasting one RXQ per VF. Signed-off-by:

The statistics registers have write-clear behaviour, which means we will lose any increment between the read and write. Mitigate this by only clearing when we read a non-zero value, so we will never falsely report a total of zero. This also saves time as we only handle error statistics here and they won't often be incremented. Signed-off-by:

There are many different sets of registers implemented by the different versions of this controller, and we can only expect this to get more complicated in future. Limit how much ethtool needs to know by including an explicit bitmap of which registers are included in the dump, allowing room for future growth in the number of possible registers. As I don't have datasheets for all of these, I've only included registers that are: - defined in all 5 register type arrays, or - used by the driver, or - documented in the datasheet I have Add one new capability flag so we can tell whether the RTRATE register is implemented. Delete the TSU_ADRL0 and TSU_ADR{H,L}31 definitions, as they weren't used and the address table is already assumed to be contiguous. Signed-off-by: -

Eric W. Biederman says: ==================== Basic MPLS support take 2 On top of my two pending neighbour table prep patches here is the mpls support refactored to use them, and edited to not drop routes when an interface goes down. Additionally the addition of RTA_LLGATEWAY has been replaced with the addtion of RTA_VIA. RTA_VIA being an attribute that includes the address family as well as the address of the next hop. MPLS is at it's heart simple and I have endeavoured to maintain that simplicity in my implemenation. This is an implementation of a RFC3032 forwarding engine, and basic MPLS egress logic. Which should make linux sufficient to be a mpls forwarding node or to be a LSA (Label Switched Router) as it says in all of the MPLS documents. The ingress support will follow but it deserves it's own discussion so I am pushing it separately. ==================== Signed-off-by:
