It was observed that AP beacons would not reflect correct regulatory
information upon starting AP in A band. This was because of missing
AP config band update in set_channel of start_ap.

Having only 128K as limit for TSQ introduced 30% regression in guest

This patch raises the limit to 256K. This reduces the regression to 8%.

tcp_v4_rcv() checks the following before calling tcp_v4_do_rcv():

if (th->doff < sizeof(struct tcphdr) / 4)
    goto bad_packet;
if (!pskb_may_pull(skb, th->doff * 4))
    goto discard_it;

So following check in tcp_v4_do_rcv() is redundant
and "goto csum_err;" is wrong anyway.

if (skb->len < tcp_hdrlen(skb) || ...)
	goto csum_err;

A second check can be removed after no_tcp_socket label for same reason.

Same tests can be removed in tcp_v6_do_rcv()

Note : short tcp frames are not properly accounted in tcpInErrs MIB,
because pskb_may_pull() failure simply drops incoming skb, we might
fix this in a separate patch.

Intel Wired LAN Driver Updates 2015-06-03

This series contains updates to e1000e only.

Yanir provides 8 fixes and 1 version bump for e1000e.  First fix resolves
a possible unit hang if multiple descriptors are available in the rings
during reset or runtime suspend.  Fixed a warning on SPARC compile based
on a suggested solution from Alex Duyck.  Fixed a logical error, where
a "if" condition under which a flush should occur, was revered.  Fixed
a hardware issue that prevented i219 from working in legacy interrupts
mode.  Fixed the hardware clock configuration and suprious non-linear
increment.  Lastly, fixed a system hang which occurred during execution
of "ethtool -t <NIC>", by disabling MULR for the loopback test to avoid
the hand state.

Allow eBPF programs attached to classifier/actions to call
bpf_clone_redirect(skb, ifindex, flags) helper which will
mirror or redirect the packet by dynamic ifindex selection
from within the program to a target device either at ingress
or at egress. Can be used for various scenarios, for example,
to load balance skbs into veths, split parts of the traffic
to local taps, etc.
