There are bunch of reports that this check fails at least on Nuvoton
NCT6776 chips. I don't see why this check needed there, and Linux does
not have it either. So far this check only made watchdogd unstopable.

For some reason firmware sends Port Database Changed notifications in case
of explicit login requests from the driver when target port is unavailabe.
Those notifications don't give driver any new information, but only cause
infinite scan loop.
Now that we're decap'ing A-MPDU frame, the firmware is only giving us
PHY status information for the whole PPDU, rather than duplicatig it
per frame.
So, we fake it by maintaining the RSSI that we saw in the node struct
and reuse it.
This prevents us from getting some pretty garbage looking default RSSI
values, which shows up as RSSI values of like "3" or "4" when doing
active traffic.
Tested:
* RTL8188EU, STA mode
basis.
2. grcdump can be taken at failure points by invoking bxe_grc_dump() when
trigger_grcdump sysctl flag is set. When grcdump is taken grcdump_done
sysctl flag is set.
3. grcdump_done can be monitored by the user to retrieve the grcdump.

The size of the reply can be different from the size of the command in
case a debug firmware asserts. fw_asrt() needs the entire reply in
order to decode the location of the assert.

2. For SIOCSIFFLAGS call bxe_init_locked() only if !BXE_STATE_DISABLED
3. remove code not needed in bxe_init_internal_common()

Previously we had to do it synchronously because we could not drop the lock
due to potential scratch memory use conflicts. Previous commits fixed that
collision, so here it goes -- slower and less reliable external requests
are executed asynchronously without spinning in tight loop and with more
safe timeout handling.
This fixes a conflict with the M_B macro in powerpc's
<machine/db_machdep.h> exposed by the recent addition of DDB commands
to the cxgbe driver.

Usually IOCBs should be put on queue for asynchronous processing and should
not require additional DMA memory. But there are some cases like aborts and
resets that for external reasons has to be synchronous. Give those cases
separate 2*64 byte DMA area to decouple them from other DMA scratch area
users, using it for asynchronous requests.
While the same update is also available for 24xx chips, it seems have
a problem with disabling virtual ports -- firmware handles the request,
but does not respong on it, causing timeout in driver.

10Ge and 40Ge. More rings are still allowed by manual configuration.

"how" argument is passed as value of int* pointer to callback
function but dereferenced as char* so only one byte taken into
into account. On little-endian systems it happens to work because
first byte is LSB that contains actual value, on big-endian it's
MSB and in this case it's always equal zero

This is cosmetics that simplifies identification of new ports on FC switch.
It would be good to use target name from CTL here instead of hostname, but
it is not passed here through CAM now.

VM_NUMA_ALLOC is used to enable use of domain-aware memory allocation in
the virtual memory system. DEVICE_NUMA is used to enable affinity
reporting for devices such as bus_get_domain().
MAXMEMDOM must still be set to a value greater than for any NUMA support
to be effective. Note that 'cpuset -gd' always works if MAXMEMDOM is
enabled and the system supports NUMA.
