Reconfiguring the port requires us to flush all DMA queues.  In
repeated testing we have found that RX flushes would sometimes fail
because the RX DMA engine was not properly isolated from the MACs.

Received frames must be re-clocked by the local XGXS to the 156.25 MHz
(DDR) clock of the XGMII.  If the remote clock is slightly faster this
can reduce a minimum IPG of 64 bit-times (1 cycle) to 32 bit-times
(half a cycle).  If the XMAC detects that a frame has reached the
maximum RX frame length in the same cycle that it receives one of
these reduced IPGs, it may miss the IPG, causing two valid frames to
be treated as a single invalid frame (over-length with bad CRC).

We work around this by increasing the maximum RX frame length so that
peers with matched MTU will not provoke this bug.

At probe time, falcon_reset_hw() performs a hard reset of the PHY
along with Falcon.  There is no need to perform a soft reset later,
and any access to standard MDIO registers before the PHY firmware has
booted can interrupt the boot process, making the port unusable.

When the interface is put in bridged mode, destination mac
addresses are unknown to firmware. So packets take a slow
path (lower priority) in firmware reducing performance.

Firmware can cache limited number of remote unicast mac
addresses for certain interval, if "dynamic mac learning"
mode is enabled.

Driver needs to enable this "mac learning" mode in firmware.
Currently this is done through net device class sysfs entry,
possibly this can also be done upon netlink notifications to
from bridge.
