It was once upon time so that snd_sthresh was a 16-bit quantity.
...That has not been true for long period of time. I run across
some ancient compares which still seem to trust such legacy.
Put all that magic into a single place, I hopefully found all
of them.
Compile tested, though linking of allyesconfig is ridiculous
nowadays it seems.

In the case of fiber and serdes adapters we were seeing issues with ethtool
-t causing kernel panics due to null function pointers. To prevent this we
need to exit out of the phy reset code in the event that we do not have a
valid phy.

Our SGMII phy code was incomplete in that it was not actually placing the
phy in SGMII mode and as a result the PHY was not able to establish a link
when connected to a non serdes link partner. This patch updates the code
to combine the SGMII/serdes PCS init and to add the necessary reset.

Currently the media type detection for CX4 adapters lumps them into a
type of fiber. This causes some strange fallout when firmware verification
is done on the NIC, and certain fiber NIC rules get enforced incorrectly.
This patch introduces a new media type for CX4, and puts both 82598 and
82599 CX4 adapters into this bucket.

The packet split feature was recently moved out of the adapter-wide flags
feature field and into a per-Rx ring feature field. In the process, packet
split isn't properly disabled in the Rx ring if the adapter has it globally
disabled, followed by a device reset.
This won't impact the driver today, since it's always in packet split mode.
However, this will prevent any pitfalls if someone disables packet split on
the adapter in the future and doesn't disable it in each ring.

because I overlooked that netlink_table_grab() will
schedule, thinking it was just the rwlock. However,
in the contention case, that isn't actually true.
Fix this by letting the code grab the netlink table
lock first and then the RCU for netns protection.

Fixed up trivial conflicts:
- arch/x86/include/asm/socket.h
converted to <asm-generic/socket.h> in the x86 tree. The generic
header has the same new #define's, so that works out fine.
- drivers/net/tun.c
fix conflict between 89f56d1e9 ("tun: reuse struct sock fields") that
switched over to using 'tun->socket.sk' instead of the redundantly
available (and thus removed) 'tun->sk', and 2b980dbd ("lsm: Add hooks
to the TUN driver") which added a new 'tun->sk' use.

xen: only enable interrupts while actually blocking for spinlock
xen: make -fstack-protector work under Xen
When we close a file, we remove preallocated blocks from it. But this
truncation was not protected by i_mutex and thus it could have raced with a
write through a different fd and cause crashes or even filesystem corruption.
