dev_hard_start_xmit() does two things, it first validates and canonicalizes the SKB, then it actually sends it. Make a set of helper functions for doing the first part. Signed-off-by: NDavid S. Miller <davem@davemloft.net>

There is a slight policy change happening here as well. The previous code would drop the entire rest of the GSO skb if any of them got, for example, a congestion notification. That makes no sense, anything NET_XMIT_MASK and below is something like congestion or policing. And in the congestion case it doesn't even mean the packet was actually dropped. Just continue until dev_xmit_complete() evaluates to false. Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Tom Herbert says: ==================== net: Checksum offload changes - Part VI I am working on overhauling RX checksum offload. Goals of this effort are: - Specify what exactly it means when driver returns CHECKSUM_UNNECESSARY - Preserve CHECKSUM_COMPLETE through encapsulation layers - Don't do skb_checksum more than once per packet - Unify GRO and non-GRO csum verification as much as possible - Unify the checksum functions (checksum_init) - Simplify code What is in this sixth patch set: - Clarify the specific requirements of devices returning CHECKSUM_UNNECESSARY (comments in skbuff.h). - Add csum_level field to skbuff. This is used to express how many checksums are covered by CHECKSUM_UNNECESSARY (stores n - 1). - Change __skb_checksum_validate_needed to "consume" each checksum as indicated by csum_level as layers of the the packet are parsed. - Remove skb_pop_rcv_encapsulation, no longer needed in the new csum_level model. - Allow GRO path to "consume" checksums provided in CHECKSUM_UNNECESSARY and to report new verfied checksums for use in normal path fallback. - Add proper support to SCTP to accept CHECKSUM_UNNECESSARY to validate header CRC. - Modify drivers to set skb->csum_level instead of setting skb->encapsulation to indicate validation of an encapsulated checksum on receive. v2: Allocate a new 16 bits for flags in skbuff. Please review carefully and test if possible, mucking with basic checksum functions is always a little precarious :-) ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Allow GRO path to "consume" checksums provided in CHECKSUM_UNNECESSARY and to report new checksums verfied for use in fallback to normal path. Change GRO checksum path to track csum_level using a csum_cnt field in NAPI_GRO_CB. On GRO initialization, if ip_summed is CHECKSUM_UNNECESSARY set NAPI_GRO_CB(skb)->csum_cnt to skb->csum_level + 1. For each checksum verified, decrement NAPI_GRO_CB(skb)->csum_cnt while its greater than zero. If a checksum is verfied and NAPI_GRO_CB(skb)->csum_cnt == 0, we have verified a deeper checksum than originally indicated in skbuf so increment csum_level (or initialize to CHECKSUM_UNNECESSARY if ip_summed is CHECKSUM_NONE or CHECKSUM_COMPLETE).

This patch: - Clarifies the specific requirements of devices returning CHECKSUM_UNNECESSARY (comments in skbuff.h). - Adds csum_level field to skbuff. This is used to express how many checksums are covered by CHECKSUM_UNNECESSARY (stores n - 1). This replaces the overloading of skb->encapsulation, that field is is now only used to indicate inner headers are valid. - Change __skb_checksum_validate_needed to "consume" each checksum as indicated by csum_level as layers of the the packet are parsed. - Remove skb_pop_rcv_encapsulation, no longer needed in the new csum_level model.

This patch adds support to run Power On Self Test (POST) for 83xx adapters. POST can be run in 3 different speed modes : i) Fast mode (takes about 690 ms) ii) Medium mode (takes about 2930 ms) iii) Slow mode (takes about 7500 ms) To run POST, firmware file with name "83xx_post_fw.bin" should be present under /lib/firmware directory. load_fw_file module parameter is used to specify POST operation and its speed mode. load_fw_file = 2 : Fast mode load_fw_file = 3 : Medium mode load_fw_file = 4 : Slow mode Signed-off-by: NShahed Shaikh <shahed.shaikh@qlogic.com> Signed-off-by: NDavid S.

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2014-08-27 This series contains updates to i40e and i40evf. Carolyn provides two patches, first changes the wording of the flow director add/remove and asynchronous failure messages to include the fd_id to try and add some way to track the operations on a given fd_id. Second adds a check during handle_link_event for unqualified modules when link is down and there is a module plugged in. Anjali provides four patches to i40e/i40evf. First update flow director messages so that a user can tell if a filter was added or deleted. Then updates the ATR policy to not auto-disable ATR when we have errors in programming. The disabling of ATR when we got programming errors was buggy and was still adding new rules and causing continuous errors. With this policy change, we flush instead when we see too many errors. In addition she adds a flow director flush counter to ethtool to help know how many times the interface had to flush and replay the flow director filter table. Updates the driver to ignores a driver perceived transmit hang if the number of descriptors pending is less than 4, and instead log a stat when this situation happens. This is because the queue progresses forward and the stack never experiences a real hang in these situations. Shannon provides three patches for i40e/i40evf, first enables the l2tsel bit on receive queue contexts that are assigned to VFs so that the VF can get the stripped VLAN tag. Then adds a max buffer size parameter to the print helper to be sure the code knows when to stop. Lastly, remove the complaint when removing the default MAC VLAN filter. This was because old firmware had an incorrect MAC VLAN filter that needed to be replaced at startup, and now newer firmware does not have this problem. So now we only add the new filter if the removal succeeded and no need to complain if the removal fails. Ashish provides a change to vsi->num_queue_pairs to equal the number that is configured by the VF. This limits the number of queues that are enabled/disabled and fixes the mismatch case for when a VF configures fewer queues than is allocated to it by the PF. ==================== Signed-off-by: NDavid S.
