Dmitry Eremin-Solenikov a0b4a738e0 wpan-phy: allow specifying a per-page channel mask
IEEE 802.15.4-2006 defines channel pages that hold channels (max 32 pages,
27 channels per page). Allow the driver to specify supported channels
on pages, other than the first one.

Gilad Ben-Yossef 05eaade278 tcp: Do not call IPv4 specific func in tcp_check_req
Calling IPv4 specific inet_csk_route_req in tcp_check_req
is a bad idea and crashes machine on IPv6 connections, as reported
by Valdis Kletnieks

Also, all we are really interested in is the timestamp
option in the header, so calling tcp_parse_options()
with the "estab" set to false flag is an overkill as
it tries to parse half a dozen other TCP options.

We know whether timestamp should be enabled or not
using data from request_sock.

Matt Carlson 32e5a8d651 tg3 / broadcom: Add code to disable rxc refclk
The 5785 does not use the RXC reference clock.  Turning it off is
desirable as it saves power.

By default, the 50610 enables the RXC reference clock and the 50610M
disables it.  Presumably this is one of the reasons why the hardware
architect chose one over the other.

Adding a "rx reference clock disable" flag is not the ideal way to
describe the option, as it would force the MAC using a 50610M to set
the flag.  Ideally we want the flags to represent opt-in behavior that
deviates from hardware defaults.  Furthermore, the lack of a
"disable" flag implies that the requester wants the rx reference clock
enabled, which doesn't necessarily follow.

By presenting the option as a passive statement (rx reference clock
unused) rather than a command, I hope to convey an opt-in option to
disable the rx reference clock that falls back to hardware defaults if
not set.  A secondary benefit of this is that it keeps the
intelligence about phy defaults in the broadcom module where it belongs
and allows the broadcom module more latitude should a bug arise.

Rather than unnecessarily burn an extra bit in the dev_flags member in
an attempt to enumerate all possible combinations, this patch take a
more course grained approach and labels the option as "clear all bits".
