Since SR[0] in the (readonly) XGI330_StandTable is always 0x01 we can
skip or'ing with 0x01 and make the code simpler by removing the if
statements.
Since this function is the only user of the XGI330_StandTable we can
also include the unconditional |= 0x20 into the input data and move the
assignment to SR1 into the loop, which I prefer to start at 0.

Since the smaller LCDRefreshIndex is contained identically in LCDARefreshIndex
we can simply use LCDARefreshIndex and skip the if/else.
Since LCDARefreshIndex is only used readonly and contains only small
unsigned values we also change its declaration to const u8.
In order to prevent an out-of-bounds access I changed the mask from 0x0F
to 0x07 and added a dummy value.

Currently, when the PF driver is unloaded and re-loaded while VFs are attached
to VMs, it loses control of its VFs.
The PF driver now uses the newly defined/created GET_IFACE_LIST cmd
(available in FW ver >= 4.6) to query the if_id of the VFs
(enabled in its previous life). The PF driver then uses the if_id for
further VF configuration.
The GET_IFACE_MAC_LIST cmd has also implemented in BE3 FW for PF to
query pmac-ids used by its VFs.

It is normal for minidrivers accumulating frames to return NULL
from their tx_fixup function. We do not want to count this as a
drop, or log any debug messages. A different exit path is
therefore chosen for such drivers, skipping the debug message
and the tx_dropped increment.
The test for accumulating drivers was however completely bogus,
making the exit path selection depend on whether the user had
enabled tx_err logging or not. This would arbitrarily mess up
accounting for both accumulating and non-accumulating minidrivers,
and would result in unwanted debug messages for the accumulating
drivers.
Fix by testing for FLAG_MULTI_PACKET instead, which probably was
the intention from the beginning. This usage match the documented
behaviour of this flag:
Indicates to usbnet, that USB driver accumulates multiple IP packets.
Affects statistic (counters) and short packet handling.
