Add support for SRIOV VF min rate guarantee by using the TSAR BW share
weights mechanism.
The TSAR BW share vport attribute represents the weight of that vport
among the other vports weights which means that the actual vport BW
percentage is the same vport weight percentage among the total vports
weights sum.

The E-Switch FDB size was hard coded to 8k. Change it to be
min(max eswitch table size, max flow counters * num flow groups)
where the max values are read from the firmware and the number of
flow groups is hard-coded as before this change.
We don't know upfront the division of flows to group. This setup allows
each group to be of size up to the where we want to support (we mandate
pairing of flows with counters for offloading). Thus, we don't expect
multiple occurences for a group which in turn adds steering hops.

The EMAC has an internal PHY that is often called the "SGMII". This
SGMII is also connected to an external PHY, which is managed by phylib.
These dual PHYs often cause confusion. In this case, the data structure
for managing the SGMII was mis-named and located in the wrong header file.
Structure emac_phy is renamed to emac_sgmii to clearly indicate it applies
to the internal PHY only. It also also moved from emac_phy.h (which
supports the external PHY) to emac_sgmii.h (where it belongs).
To keep the changes minimal, only the structure name is changed, not
the names of any variables of that type.

Add supporf for the SYSTEMPORT Lite Ethernet controller, this piece of hardware
is largely based on the full-blown SYSTEMPORT and differs in the following:
- no full-blown UniMAC, instead we have the MagicPacket matching from UniMAC at
same offset, and a GMII Interface Block (GIB) for the MAC-level stuff, since
we are always interfaced to an Ethernet switch which is fully Ethernet compliant
shortcuts could be made
- 16 transmit queues, whose interrupts are moved into the first Level-2 interrupt
controller bank
- slight TDMA offset change (a register was inserted after TDMA_STATUS, *sigh*)
- 256 RX descriptors (512 words) and 256 TX descriptors (not visible)
As a consequence of these two things, update the code paths accordingly to

The network stack no longer uses the last_rx member of struct net_device
since the bonding driver switched to use its own private last_rx in
commit 9f24273837 ("bonding: use last_arp_rx in slave_last_rx()").
However, some drivers still (ab)use the field for their own purposes and
some driver just update it without actually using it.
Previously, there was an accompanying comment for the last_rx member
added in commit 4dc89133f4 ("net: add a comment on netdev->last_rx")
which asked drivers not to update is, unless really needed. However,
this commend was removed in commit f8ff080dac ("bonding: remove
useless updating of slave->dev->last_rx"), so some drivers added later
on still did update last_rx.
Remove all usage of last_rx and switch three drivers (sky2, atp and
smc91c92_cs) which actually read and write it to use their own private
copy in netdev_priv.
