The new implementation is supposed to be able to cope with changes to

The set of the flag is not neccessary there, because the only current
user of the cpu_set_user_tls() is create_thread(), which calls
cpu_set_upcall() before and cpu_set_upcall() itself sets PCB_FULL_IRET.
Change the function for consistency and preserve existing KPI for now.

This allows hints to override the TX and RX chainmask.
These hints are:

hint.ath.X.tx_chainmask
They can be set at either boot time or in kenv before the module is loaded.

Add an ar5416SetCapability() function, which contains logic to override

If an IPv6 packet has extension headers the kernel needs to deal with it
itself. For the rest it can set various CSUM_XXX flags and the driver
will act on them.
the kernel allocated a buffer but did not zero it as it was about
to be completely filled by a uiomove() from the user's buffer.
However, if the uiomove() failed, the old contents of the buffer
could be exposed especially if the file was being mmap'ed. The
fix was to always zero the buffer when it was allocated.
This change first attempts the uiomove() to the newly allocated
(and dirty) buffer and only zeros it if the uiomove() fails. The
effect is to eliminate the gratuitous zeroing of the buffer in
the usual case where the uiomove() successfully fills it.

Reading register $29 with RDHWR is becoming the de-facto standard to
implement TLS. According to linux-mips wiki, MIPS Technologies has
reserved hardware register $29 for ABI use. Furthermore current GCC
makes the following assumptions:
- RDHWR is natively available or otherwise emulated by the kernel
- Register $29 holds the TLS pointer
