====================
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 cd7d8498c9a5 ("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.

We had various issues in the past when TCP stack was modifying
gso_size/gso_segs while clones were in flight.
Commit c52e2421f73 ("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()

In commit cd7d8498c9a5 ("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...)

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.

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.

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.

When programming the start of a periodic output, the code wrongly places
the seconds value into the "low" register and the nanoseconds into the
"high" register. Even though this is backwards, it slipped through my
testing, because the re-arming code in the interrupt service routine is
correct, and the signal does appear starting with the second edge.
This patch fixes the issue by programming the registers correctly.

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.

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.
