Extend the size of the local rx_buffer_size variable to account for
larger buffer sizes possible on 82580, i350 chips.
From i350 datasheet, 6.2.10 Initialization Control 4 (LAN Base Address
+ Offset 0x13):
When 4 ports are enabled maximum buffer size is 36 KB. When 2 ports are
enabled maximum buffer size is 72 KB. When only a single port is
enabled maximum buffer size is 144 KB.
and 8.3:
The overall available internal buffer size in the I350 for all ports is
144 KB for receive buffers and 80 KB for transmit Buffers. Disabled
ports memory can be shared between active ports and sharing can be
asymmetric. The default buffer size for each port is loaded from the
EEPROM on initialization.
From the reporter:
But for I350 when only 2 ports are used PBA size can be set as 72KB
(see datasheet RXPbsize or e1000_rxpbs_adjust_82580 function in
e1000_82575.c). In this case calculating the rx_buffer_size overflows
as 0x0048 << 10 = 73728 or 0x12000 pushed into u16. It is then set as
0x2000 or 8192.

Currently if an e1000 interface is set to a fixed media configuration,
for gigabit, it will participate in auto-negotiation as required by
IEEE 802.3-2018 Clause 37. However, if set to fixed media configuration
for 100 or 10, it does NOT participate in auto-negotiation.
By my reading of Clauses 28 and 37, while auto-negotiation is optional
for 100 and 10, it is not prohibited and is, in fact, "highly
recommended".
This patch enables auto-negotiation for fixed 100 and 10 media
configuration, in a similar manner to that already performed for 1000.
I.e., the patch enables advertising of just the manually configured
settings with the goal of allowing the remote end to match the manually
configured settings if it has them available.
To be clear, this patch does NOT allow an em(4) interface that has been
manually configured with specific media settings to respond to
auto-negotiation by then configuring different parameters to those that
were manually configured. The intent of this patch is to fully comply
with the requirements of Clause 37, but for 100 and 10.
The need for this has arisen on an em(4) link where the other end is
under a different administrative control and is set to full
auto-negotiation. Due to the cable length GigE is not working well. It
is desired to set the em(4) end to "media 100baseTX mediatype
full-duplex" which does work when both ends are configured that way.
Currently, because em(4) does not participate in autoneg for this
setting, the remote defaults to half-duplex - i.e., there's a duplex
mismatch and things don't work. With this patch, em(4) would inform the
remote that it has only 100baseTX full, the remote would match that and
it will work.

The logic that sets iri_vtag and M_VLANTAG does not handle the
case where the 802.11q VLAN tag is 0. Fix this issue across
the iflib drivers. While there, also improve and align the
VLAN tag check extraction, by moving it outside the RX descriptor
loop, eliminating a local variable and additional checks.

Since isc_capenable (private copy of ifp->if_capenable) is
now synchronized to if_capenable, use it in the drivers
when checking the IFCAP_* bits.
This results in better cache usage and avoids indirection

The e1000 drivers (em, lem, igb) are currently looking at the
iflib copies of the capabilities bitvectors (scctx->isc_capabilities
and scctx->isc_capenable) rather than the ifnet ones
(ifp->if_capabilities and ifp->if_capenable). However, the latter
are the ones that are actually updated by ifconfig and that should
be used by the drivers during interface operation. The former are
set by the driver on interface attach (for iflib internal use)
and should not be used anymore by the driver.
This patch fixes the e1000 driver to use the correct bitvectors.
