The 4.16 DTS import brought in emac support for the a83t. Since these
boards' DTS is pulled from /boot and I forgot to hook these up to the build,
they should be fairly safe to go away.
The a83t-sid and h3-sid overlays are still relevant. a83t-sid will likely
come in with 4.18 DTS.
Since the move to SMP NIC driver locking has had to go through serious
contortions using mtx around long running hardware operations. This moves
iflib past that.
Individual drivers may now sleep when appropriate.

Without the suspend method the watchdog may fire in S1 state. Without

Not sure if watchdog(4) should participate in the suspend actions.

This patch adds two missing LIST_INIT()s. Found by inspection.
In practice, these are currently no-ops, since the structure they are
in is malloc'd with M_ZERO and all LIST_INIT does is set the pointer
in the list head to NULL. (In other words, the M_ZERO has already
correctly initialized it.)

According to the 802.1Q-2014 9.6 VLAN Tag Control Information, VID value 0
means that there is no VLAN tag assigned to the packet, and only PCP and
DEI values from the tag are meaningful. Current flow table programming
filter out such packets.
When programming VLAN filter for flow table, unconditionally add rule which
accept packets with VLAN id 0. The packets are already handled correctly
by the network stack.

Admin pass-through requests took controller lock before the queue lock,
but in case of request submission to a failed controller controller lock
was taken after the queue lock. Fix that by reducing the lock scopes and

Current interface to the gntdev in FreeBSD is wrong, and mostly worked
out of luck before the PTI FreeBSD fixes, when kernel and user-space
where sharing the same page tables.
On FreeBSD ioctls have the size of the passed struct encoded in the
ioctl number, because the generic ioctl handler in the OS takes care
of copying the data from user-space to kernel space, and then calls
the device specific ioctl handler. Thus using ioctl structs with
variable sizes is not possible.
The fix is to turn the array of structs at the end of
ioctl_gntdev_alloc_gref and ioctl_gntdev_map_grant_ref into pointers,
that can be properly accessed from the kernel gntdev driver using the
copyin/copyout functions. Note that this is exactly how it's done for
the privcmd driver.
