bb263e18f4 atp: remove set_rx_mode_8012()
Building atp.o triggers this GCC warning:
    drivers/net/ethernet/realtek/atp.c: In function ‘set_rx_mode’:
    drivers/net/ethernet/realtek/atp.c:871:26: warning: ‘mc_filter[0]’ may be used uninitialized in this function [-Wuninitialized]

GCC is correct. In promiscuous mode 'mc_filter' will be used
uninitialized in set_rx_mode_8012(), which is apparently inlined into
set_rx_mode().

But it turns out set_rx_mode_8012() will never be called, since
net_local.chip_type will always be RTL8002. So we can just remove
set_rx_mode_8012() and do some related cleanups.

26cdfb4915 macb: Keep driver's speed/duplex in sync with actual NCFGR
When underlying phy driver restores its state very fast after being brought
down and up so that macb driver function macb_handle_link_change() was never
called with link state "down", driver's internal representation of phy speed
and duplex (bp->speed and bp->duplex) didn't change. So, macb driver sees no
reason to perform actual write to the NCFGR register, although the speed and
duplex settings in that register were reset when interface was brought down
and up. In that case actual phy speed and duplex differ from NCFGR settings.
The patch fixes that by keeping internal driver representation of speed and
duplex in sync with actual content of NCFGR.

Instead of masking head and tail every time we increment them, just let them
wrap through UINT_MAX and mask them when subscripting. Add simple accessor
functions to do the subscripting properly to minimize the chances of messing
this up.

This makes the code slightly smaller, and hopefully faster as well.  Also,
doing the ring buffer management this way will simplify things a lot when
making the ring sizes configurable in the future.
