Drivers should pull only ethernet header from page frag to skb->head. Pulling 64 bytes is too much for TCP (without options) on IPv4. However, it makes sense to pull all the frame if it fits the 128 bytes bloc allocated for skb->head, to free one page per small incoming frame. Signed-off-by:

Followup of commit 0c24604b (tcp: implement RFC 5961 4.2) As reported by Vijay Subramanian, we should send a challenge ACK instead of a dup ack if a SYN flag is set on a packet received out of window.

The usbnet API use the device ID table to store a pointer to a minidriver. Setting a generic pointer for dynamic device IDs will in most cases make them work as expected. usbnet will otherwise treat the dynamic IDs as blacklisted. That is rarely useful. There is no standard class describing devices supported by this driver, and most vendors don't even provide enough information to allow vendor specific wildcard matching. The result is that most of the supported devices must be explicitly listed in the device table. Allowing dynamic IDs to work both simplifies testing and verification of new devices, and provides a way for end users to use a device before the ID is added to the driver. Signed-off-by:

This change is meant to make the code much more readable for MTQC and MRQC configuration. The big change is that I simplified much of the logic so that we are essentially handling just 4 cases and their variants. In the cases where RSS is disabled we are actually just programming the RETA table with all 1s resulting in a single queue RSS. In the case of SR-IOV I am treating that as a subset of VMDq. This all results int he following configuration for the hardware: DCB En Dis VMDq En VMDQ/DCB VMDq/RSS Dis DCB/RSS RSS Cc: John Fastabend <john.r.fastabend@intel.com> Signed-off-by:

This change cleans up some of the logic in an attempt to try and simplify things for how we are configuring DCB w/ RSS. In this patch I basically did 3 things. I updated the logic for getting the first register index. I applied the fact that all TCs get the same number of queues to simplify the looping logic in caching the DCB ring register. Finally I updated how we configure the RQTC register to match the fact that all TCs are assigned the same number of queues. Cc: John Fastabend <john.r.fastabend@intel.com> Signed-off-by:

It makes much more sense for us to configure the real number of Tx and Rx queues in the ixgbe_open call than it does in ixgbe_set_num_queues. By setting the number in ixgbe_open we can avoid a number of unecessary updates and only have to make the calls once. Signed-off-by:

Previously we were exiting without cleaning up the memory internally on the ixgbe_setup_rx_resources and ixgbe_setup_tx_resources calls. Instead of forcing the caller to clean things up for us we should instead just unwind the rings and free the memory as we go. This way we can more gracefully clean up the rings in the event of an allocation failure. Signed-off-by:

When the link status changes on the PF we need to notify the VFs. In order to do this we should ping all of the VFs in order to trigger a link status change on them as well. This fixes issues in which the PF would reset, but the VF didn't because the NAK flag was not set in the VF mailbox. Signed-off-by:

These patches implement the final mechanism necessary to really allow us to go without the route cache in ipv4. We need a place to have long-term storage of PMTU/redirect information which is independent of the routes themselves, yet does not get us back into a situation where we have to write to metrics or anything like that. For this we use an "next-hop exception" table in the FIB nexthops. The one thing I desperately want to avoid is having to create clone routes in the FIB trie for this purpose, because that is very expensive. However, I'm willing to entertain such an idea later if this current scheme proves to have downsides that the FIB trie variant would not have. In order to accomodate this any such scheme, we need to be able to produce a full flow key at PMTU/redirect time. That required an adjustment of the interface call-sites used to propagate these events. For a PMTU/redirect with a fully specified socket, we pass that socket and use it to produce the flow key. Otherwise we use a passed in SKB to formulate the key. There are two cases that need to be distinguished, ICMP message processing (in which case the IP header is at skb->data) and output packet processing (mostly tunnels, and in all such cases the IP header is at ip_hdr(skb)). We also have to make the code able to handle the case where the dst itself passed into the dst_ops->{update_pmtu,redirect} method is invalidated. This matters for calls from sockets that have cached that route. We provide a inet{,6} helper function for this purpose, and edit SCTP specially since it caches routes at the transport rather than socket level. Signed-off-by:

In a regime where we have subnetted route entries, we need a way to store persistent storage about destination specific learned values such as redirects and PMTU values. This is implemented here via nexthop exceptions. The initial implementation is a 2048 entry hash table with relaiming starting at chain length 5. A more sophisticated scheme can be devised if that proves necessary. Signed-off-by:

Some interface statistics are computed in such a way that they can sometimes decrease (and even underflow). Since the computed value will never be greater than the true value, we fix this by only storing the computed value when it increases. Signed-off-by:

Currently VF queues and drivers may remain active during this test. This could cause memory corruption or spurious test failures. Therefore we reset the port/function before running these tests on Siena. On Falcon this doesn't work: we have to do some additional initialisation before some blocks will work again. So refactor the reset/register-test sequence into an efx_nic_type method so efx_selftest() doesn't have to consider such quirks. In the process, fix another minor bug: Siena does not have an 'invisible' reset and the self-test currently fails to push the PHY configuration after resetting. Passing RESET_TYPE_ALL to efx_reset_{down,up}() fixes this. Signed-off-by:
