Some configurations need delay between the "write completed" indication and new write to work reliably. Realtek driver seems to use longer delay when polling the "write complete" bit, so it waits long enough between writes with high probability (but could probably break too). This patch adds a new udelay to make sure we wait unconditionally some time after the write complete indication. This caused a regression with XID 18000000 boards when the board specific phy configuration writing many mdio registers was added in commit 2e955856 (r8169: phy init for the 8169scd). Some of the configration mdio writes would almost always fail, and depending on failure might leave the PHY in non-working state. Signed-off-by:

v2: changed bonding module version, modified to apply on top of changes from previous patch in series, and updated documentation to elaborate on multiqueue awareness that now exists in bonding driver. This patch give the user the ability to control the output slave for round-robin and active-backup bonding. Similar functionality was discussed in the past, but Jay Vosburgh indicated he would rather see a feature like this added to existing modes rather than creating a completely new mode. Jay's thoughts as well as Neil's input surrounding some of the issues with the first implementation pushed us toward a design that relied on the queue_mapping rather than skb marks. Round-robin and active-backup modes were chosen as the first users of this slave selection as they seemed like the most logical choices when considering a multi-switch environment. Round-robin mode works without any modification, but active-backup does require inclusion of the first patch in this series and setting the 'all_slaves_active' flag. This will allow reception of unicast traffic on any of the backup interfaces. This was tested with IPv4-based filters as well as VLAN-based filters with good results. More information as well as a configuration example is available in the patch to Documentation/networking/bonding.txt. Signed-off-by:

v2: changed parameter name from 'keep_all' to 'all_slaves_active' and skipped setting slaves to inactive rather than creating a new flag at Jay's suggestion. In an effort to suppress duplicate frames on certain bonding modes (specifically the modes that do not require additional configuration on the switch or switches connected to the host), code was added in the generic receive patch in 2.6.16. The current behavior works quite well for most users, but there are some times it would be nice to restore old functionality and allow all frames to make their way up the stack. This patch adds support for a new module option and sysfs file called 'all_slaves_active' that will restore pre-2.6.16 functionality if the user desires. The default value is '0' and retains existing behavior, but the user can set it to '1' and allow all frames up if desired. Signed-off-by:

We can avoid an unecessary cache miss by checking if the skb is non-linear before accessing gso_size/gso_type in skb_warn_if_lro, the same can also be done to avoid a cache miss on nr_frags if data_len is 0. Signed-off-by:

Eric Dumazet authored
I believe a moderate SYN flood attack can corrupt RFS flow table (rps_sock_flow_table), making RPS/RFS much less effective. Even in a normal situation, server handling short lived sessions suffer from bad steering for the first data packet of a session, if another SYN packet is received for another session. We do following action in tcp_v4_rcv() : sock_rps_save_rxhash(sk, skb->rxhash); We should _not_ do this if sk is a LISTEN socket, as about each packet received on a LISTEN socket has a different rxhash than previous one. -> RPS_NO_CPU markers are spread all over rps_sock_flow_table. Also, it makes sense to protect sk->rxhash field changes with socket lock (We currently can change it even if user thread owns the lock and might use rxhash) This patch moves sock_rps_save_rxhash() to a sock locked section, and only for non LISTEN sockets.

xfrm triggers a warning if dst_pop() drops a refcount on a noref dst. This patch changes dst_pop() to skb_dst_pop(). skb_dst_pop() drops the refcnt only on a refcounted dst. Also we don't clone the child dst_entry, so it is not refcounted and we can use skb_dst_set_noref() in xfrm_output_one(). Signed-off-by:

Probably no one has used this driver on big-endian systems, since it was setting up descriptor swapping if CONFIG_BIG_ENDIAN is set, which it never is, since that symbol is not mentioned anywhere else in the kernel source. Switch this test to a check for __BIG_ENDIAN so it has a chance at working. Signed-off-by:

A single shared memory region used to communicate with firmware is mapped into both PCI PFs of the SFC9020 and SFL9021. Drivers must be able to identify which port they are addressing in order to use the correct sub-region. Currently we use the PCI function number, but the PCI address may be virtualised. Use the CS_PORT_NUM register field defined for just this purpose. Signed-off-by:
