From: Steve Hodgson <shodgson@solarflare.com>

Currently we initiate MAC stats DMA and busy-wait for completion when
stats are requested.  We can improve on this with a periodic timer to
initiate and poll for stats, and opportunistically poll when stats are
requested.

Since efx_nic::stats_disable_count and efx_stats_{disable,enable}()

macvlan: implement bridge, VEPA and private mode

This allows each macvlan slave device to be in one
of three modes, depending on the use case:

MACVLAN_PRIVATE:
  The device never communicates with any other device
  on the same upper_dev. This even includes frames
  coming back from a reflective relay, where supported
  by the adjacent bridge.

MACVLAN_VEPA:
  The new Virtual Ethernet Port Aggregator (VEPA) mode,
  we assume that the adjacent bridge returns all frames
  where both source and destination are local to the
  macvlan port, i.e. the bridge is set up as a reflective
  relay.
  Broadcast frames coming in from the upper_dev get
  flooded to all macvlan interfaces in VEPA mode.
  We never deliver any frames locally.

MACVLAN_BRIDGE:
  We provide the behavior of a simple bridge between
  different macvlan interfaces on the same port. Frames
  from one interface to another one get delivered directly
  and are not sent out externally. Broadcast frames get
  flooded to all other bridge ports and to the external
  interface, but when they come back from a reflective
  relay, we don't deliver them again.
  Since we know all the MAC addresses, the macvlan bridge
  mode does not require learning or STP like the bridge
  module does.

CSR_INT_COALESCING previously had only one, but now has two single-byte fields.
With only one single-byte field (lowest order byte) it was okay to write via
iwl_write32(), but now with two, an iwl_write32() to the lower order field
clobbers the other field (odd-address CSR_INT_PERIODIC_REG, offset 0x5), and an
iwl_write32() to CSR_INT_PERIODIC_REG could clobber the lowest byte of the
next-higher register (CSR_INT, offset 0x8).

Fortunately, no bad side effects have been produced by the iwl_write32()
usage, due to order of execution (low order byte was always written before
higher order byte), and the fact that writing "0" to the low byte of the
next higher register has no effect (only action is when writing "1"s).

Nonetheless, this cleans up the accesses so no bad side effects might occur
in the future, if execution order changes, or more bit fields get added to
CSR_INT_COALESCING.
