ath: DFS - limit number of potential PRI sequences
In the PRI detector, after the current radar pulse
has been checked agains existing PRI sequences, it
is considered as part of a new potential sequence.
Previously, the condition to accept a new sequence
was to have at least the same number of pulses as
the longest matching sequence. This was wrong,
since it led to duplicates of PRI sequences.
This patch changes the acceptance criteria for new
potential sequences from 'at least' to 'more than'
the longest existing.
Detection performance remains unaffected, while
the number of PRI sequences accounted at runtime
(and with it CPU load) is reduced by up to 50%.

brcmfmac: support NVRAMs containing pci devpaths (instead of pcie)
Recently Broadcom added support for NVRAMs with entries for multiple
PCIe devices. One of the supported formats is based on prefixes defined
like: devpath0=pcie/1/4/ and entries like 0:foo=bar 0:baz=qux etc.
Unfortunately there are also a bit older devices using different way of
defining prefixes, e.g. SmartRG SR400ac (2 x BCM43602) with entries:
devpath0=pci/1/1/
devpath1=pci/2/1
Broadcom stated this old format will never be used/supported by brcmfmac
but given the simplicity of this patch I'll insist on supporting it.

tcp: double default TSQ output bytes limit
Xen virtual network driver has higher latency than a physical NIC.
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%.
This buys us more time to work out a proper solution in the long run.

tcp: remove redundant checks
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.
