This patch makes igb invoke the GRO hooks instead of LRO. As GRO has a compatible external interface to LRO this is a very straightforward replacement. Three things of note: 1) I've kept the LRO Kconfig option until we decide to enable GRO across the board at which point it can also be killed. 2) The poll_controller stuff is broken in igb as it tries to do the same work as the normal poll routine. Since poll_controller can be called in the middle of a poll, this can't be good. I noticed this because poll_controller can invoke the GRO hooks without flushing held GRO packets. However, this should be harmless (assuming the poll_controller bug above doesn't kill you first :) since the next ->poll will clear the backlog. The only time when we'll have a problem is if we're already executing the GRO code on the same ring, but that's no worse than what happens now. 3) I kept the ip_summed check before calling GRO so that we're on par with previous behaviour.

This patch makes sfc invoke the GRO hooks instead of LRO. As GRO has a compatible external interface to LRO this is a very straightforward replacement. Everything should appear identical to the user except that the offload is now controlled by the GRO ethtool option instead of LRO. I've kept the lro module parameter as is since that's for compatibility only. I have eliminated efx_rx_mk_skb as the GRO layer can take care of all packets regardless of whether GRO is enabled or not. So the only case where we don't call GRO is if the packet checksum is absent. This is to keep the behaviour changes of the patch to a minimum. Signed-off-by:

This patch makes ixgbe invoke the GRO hooks instead of LRO. As GRO has a compatible external interface to LRO this is a very straightforward replacement. As GRO uses the napi structure to track the held packets, I've modified the code paths involved to pass that along. Signed-off-by:

Since all feature-negotiation processing now takes place in feat.c, functions for producing verbose debugging output are concentrated there. New functions to print out values, entry records, and options are provided, and also a macro is defined to not always have the function name in the output line. Thanks a lot to Wei Yongjun and Giuseppe Galeota for help and discussion with an earlier revision of this patch. Signed-off-by:

This patch takes care of initialising and type-checking sysctls related to feature negotiation. Type checking is important since some of the sysctls now directly impact the feature-negotiation process. The sysctls are initialised with the known default values for each feature. For the type-checking the value constraints from RFC 4340 are used: * Sequence Window uses the specified Wmin=32, the maximum is ulong (4 bytes), tested and confirmed that it works up to 4294967295 - for Gbps speed; * Ack Ratio is between 0 .. 0xffff (2-byte unsigned integer); * CCIDs are between 0 .. 255; * request_retries, retries1, retries2 also between 0..255 for good measure; * tx_qlen is checked to be non-negative; * sync_ratelimit remains as before. Notes: ------ 1. Die s@sysctl_dccp_feat@sysctl_dccp@g since the sysctls are now in feat.c. 2. As pointed out by Arnaldo, the pattern of type-checking repeats itself in other places, sometimes with exactly the same kind of definitions (e.g. "static int zero;"). It may be a good idea (kernel janitors?) to consolidate type checking. For the sake of keeping the changeset small and in order not to affect other subsystems, I have not strived to generalise here.

This adds full support for local/remote Sequence Window feature, from which the * sequence-number-validity (W) and * acknowledgment-number-validity (W') windows derive as specified in RFC 4340, 7.5.3. Specifically, the following is contained in this patch: * integrated new socket fields into dccp_sk; * updated the update_gsr/gss routines with regard to these fields; * updated handler code: the Sequence Window feature is located at the TX side, so the local feature is meant if the handler-rx flag is false; * the initialisation of `rcv_wnd' in reqsk is removed, since - rcv_wnd is not used by the code anywhere; - sequence number checks are not done in the LISTEN state (cf. 7.5.3); - dccp_check_req checks the Ack number validity more rigorously; * the `struct dccp_minisock' became empty and is now removed.

This initialises feature negotiation from two tables, which are in turn are initialised from sysctls. As a novel feature, specifics of the implementation (e.g. that short seqnos and ECN are not yet available) are advertised for robustness. Signed-off-by:

Following the removal of the unused struct net_device * parameter from the NAPI functions named *netif_rx_* in commit 908a7a16, they are exactly equivalent to the corresponding *napi_* functions and are therefore redundant. Signed-off-by:
