I am observing consistent behavior even with bridges, so let's unlock this. xt_mac is already usable in FORWARD, too. Section 9 of http://ebtables.sourceforge.net/br_fw_ia/br_fw_ia.html#section9 says the MAC source address is changed, but my observation does not match that claim -- the MAC header is retained.

ct->proto is big(60 bytes) due to structure ip_ct_tcp, and we don't need to initialize the whole for all the other protocols.

It seems idev field in struct rtable has no special purpose, but adding extra atomic ops. We hold refcounts on the device itself (using percpu data, so pretty cheap in current kernel). infiniband case is solved using dst.dev instead of idev->dev Removal of this field means routing without route cache is now using shared data, percpu data, and only potential contention is a pair of atomic ops on struct neighbour per forwarded packet. About 5% speedup on routing test.

It is important to move nud_state outside of the often modified cache line (because of refcnt), to reduce false sharing in neigh_event_send() This is a followup of commit 0ed8ddf4 (neigh: Protect neigh->ha[] with a seqlock) This gives a 7% speedup on routing test with IP route cache disabled.

The values used to determined if the adapter is running in single or multi-function mode were previously modified to the values necessary when making the VXGE_HW_FW_API_GET_FUNC_MODE firmware call.

To enable the processing of packets while Receive Idle, move the clearing of __VXGE_STATE_CARD_UP bit in vxge_close to after it.

This completes the implementation of a circular buffer for Ack Vectors, by extending the current (linear array-based) implementation. The changes are: (a) An `overflow' flag to deal with the case of overflow. As before, dynamic growth of the buffer will not be supported; but code will be added to deal robustly with overflowing Ack Vector buffers. (b) A `tail_seqno' field. When naively implementing the algorithm of Appendix A in RFC 4340, problems arise whenever subsequent Ack Vector records overlap, which can bring the entire run length calculation completely out of synch. (This is documented on http://www.erg.abdn.ac.uk/users/gerrit/dccp/notes/\ ack_vectors/tracking_tail_ackno/ .) (c) The buffer length is now computed dynamically (i.e. current fill level), as the span between head to tail. As a result, dccp_ackvec_pending() is now simpler - the #ifdef is no longer necessary since buf_empty is always true when IP_DCCP_ACKVEC is not configured.

This patch * separates Ack Vector housekeeping code from option-insertion code; * shifts option-specific code from ackvec.c into options.c; * introduces a dedicated routine to take care of the Ack Vector records; * simplifies the dccp_ackvec_insert_avr() routine: the BUG_ON was redundant, since the list is automatically arranged in descending order of ack_seqno.

This patch brings the Ack Vector interface up to date. Its main purpose is to lay the basis for the subsequent patches of this set, which will use the new data structure fields and routines. There are no real algorithmic changes, rather an adaptation: (1) Replaced the static Ack Vector size (2) with a #define so that it can be adapted (with low loss / Ack Ratio, a value of 1 works, so 2 seems to be sufficient for the moment) and added a solution so that computing the ECN nonce will continue to work - even with larger Ack Vectors. (2) Replaced the #defines for Ack Vector states with a complete enum. (3) Replaced #defines to compute Ack Vector length and state with general purpose routines (inlines), and updated code to use these. (4) Added a `tail' field (conversion to circular buffer in subsequent patch). (5) Updated the (outdated) documentation for Ack Vector struct. (6) All sequence number containers now trimmed to 48 bits. (7) Removal of unused bits: * removed dccpav_ack_nonce from struct dccp_ackvec, since this is already redundantly stored in the `dccpavr_ack_nonce' (of Ack Vector record); * removed Elapsed Time for Ack Vectors (it was nowhere used); * replaced semantics of dccpavr_sent_len with dccpavr_ack_runlen, since the code needs to be able to remember the old run length; * reduced the de-/allocation routines (redundant / duplicate tests).

unix_dgram_poll() is pretty expensive to check POLLOUT status, because it has to lock the socket to get its peer, take a reference on the peer to check its receive queue status, and queue another poll_wait on peer_wait. This all can be avoided if the process calling unix_dgram_poll() is not interested in POLLOUT status. It makes unix_dgram_recvmsg() faster by not queueing irrelevant pollers in peer_wait.
