phy_device->supported is originally set by the PHY driver.
The ethernet driver should filter phy_device->supported to only contain
flags supported by the IP.
The IP supports setting rx and tx flow control independently,
therefore SUPPORTED_Pause and SUPPORTED_Asym_Pause should not be cleared.
If the flags are cleared, pause frames cannot be enabled (even if they
are supported by the PHY).

This is relatively small, mostly to get the SG/crypto
from stack removal fix that crashes things when VMAP
stack is used in conjunction with software crypto.
Aside from that, we have:
* a fix for AP_VLAN usage with the nl80211 frame command
* two fixes (and two preparation patches) for A-MSDU, one
to discard group-addressed (multicast) and unexpected
4-address A-MSDUs, the other to validate A-MSDU inner
MAC addresses properly to prevent controlled port bypass

If the driver is built as a module, autoload won't work because the module
alias information is not filled. So user-space can't match the registered
device with the corresponding module.

"results in segfaults in ulogd-2.0.5".
Because "struct nf_loginfo li;" is a local variable, and flags will be
filled with garbage value, not inited to zero. So if it contains 0x1,
packets will not be logged to the userspace anymore.

After Jesper commit back in linux-3.18, we trigger a lockdep
splat in proc_create_data() while allocating memory from
pktgen_change_name().
This patch converts t->if_lock to a mutex, since it is now only
used from control path, and adds proper locking to pktgen_change_name()
1) pktgen_thread_lock to protect the outer loop (iterating threads)
2) t->if_lock to protect the inner loop (iterating devices)
Note that before Jesper patch, pktgen_change_name() was lacking proper
protection, but lockdep was not able to detect the problem.
