Eric Dumazet says: ==================== tcp: defer shinfo->gso_size|type settings We put shinfo->gso_segs in TCP_SKB_CB(skb) a while back for performance reasons. This was in commit cd7d8498 ("tcp: change tcp_skb_pcount() location") This patch series complete the job for gso_size and gso_type, so that we do not bring 2 extra cache lines in tcp write xmit fast path, and making tcp_init_tso_segs() simpler and faster. ==================== Signed-off-by:

We had various issues in the past when TCP stack was modifying gso_size/gso_segs while clones were in flight. Commit c52e2421 ("tcp: must unclone packets before mangling them") fixed these bugs and added a WARN_ON_ONCE(skb_cloned(skb)); in tcp_set_skb_tso_segs() These bugs are now fixed, and because TCP stack now only sets shinfo->gso_size|segs on the clone itself, the check can be removed. As a result of this change, compiler inlines tcp_set_skb_tso_segs() in tcp_init_tso_segs() Signed-off-by:

In commit cd7d8498 ("tcp: change tcp_skb_pcount() location") we stored gso_segs in a temporary cache hot location. This patch does the same for gso_size. This allows to save 2 cache line misses in tcp xmit path for the last packet that is considered but not sent because of various conditions (cwnd, tso defer, receiver window, TSQ...) Signed-off-by:

Our goal is to touch skb_shinfo(skb) only when absolutely needed, to avoid two cache line misses in TCP output path for last skb that is considered but not sent because of various conditions (cwnd, tso defer, receiver window, TSQ...) A packet is GSO only when skb_shinfo(skb)->gso_size is not zero. We can set skb_shinfo(skb)->gso_type to sk->sk_gso_type even for non GSO packets. Signed-off-by:

tcp_gso_segment() and tcp_gro_receive() are not strictly part of TCP stack. They should not assume tcp_skb_mss(skb) is in fact skb_shinfo(skb)->gso_size. This will allow us to change tcp_skb_mss() in following patches. Signed-off-by:

Fix a BUG_ON() where CONFIG_NET_SWITCHDEV is set but the driver for a bridged port does not support switchdev_port_attr_set op. Don't BUG_ON() if -EOPNOTSUPP is returned. Also change BUG_ON() to netdev_err since this is a normal error path and does not warrant the use of BUG_ON(), which is reserved for unrecoverable errs. Signed-off-by:

TX_E_PRIO_CHANGE event is never sent for bna_tx so it doesn't need to be handled. After this change bna_tx->flags cannot contain BNA_TX_F_PRIO_CHANGED flag and it can be also eliminated. Signed-off-by:

The bna_rx_config struct member paused can be removed as it is never written and as it cannot have non-zero value the bna_rxf struct member flags also cannot have BNA_RXF_F_PAUSED value and is always zero. So the flags member can be removed as well as bna_rxf_flags enum and the code-paths that needs to have non-zero bna_rxf->flags. This clean-up makes bna_rxf_sm_paused state unsed and can be also removed. Signed-off-by: -

RXF_E_PAUSE & RXF_E_RESUME events are never sent for bna_rxf object so they needn't to be handled. The bna_rxf's state bna_rxf_sm_fltr_clr_wait and function bna_rxf_fltr_clear are unused after this so remove them also. Signed-off-by:

Parameters of all ether_addr_copy instances were checked for proper alignment. Alignment of bnad_bcast_addr is forced to 2 as the implicit alignment is 1. I have also renamed address parameter of bnad_set_mac_address() to addr. The name mac_addr was a little bit confusing as the real parameter is struct sockaddr *. v2: added __aligned directive to bnad_bcast_addr, renamed parameter of bnad_set_mac_address() (thx joe@perches.com) Signed-off-by: -

Each transport object, namely TIR and TIS, must have a transport domain number (TDN) identifier. The driver wrongly assumed that it is OK to use TDN=0 without explicit TDN allocation from the device. The TDN will also be used for isolating different processes once user mode Ethernet will be supported. Signed-off-by:

When NETIF_F_SG is set, each send WQE may have a different size since each skb can have different number of fragments as of LSO header etc. This implies that a given WQE may wrap around the send queue, i.e begin at its end and continue at its start. While it is legal by the device spec, we preferred a solution that avoids it - when building of current WQE is done, if the next WQE may wrap around the send queue, fill the send queue with NOPs WQEs till its end, so that the next WQE will begin at send queue start. NOP WQE for itself cannot wrap around the send queue since it is of minimal size - 64 bytes, and all send WQEs are a multiple of that size. Signed-off-by:
