sfc: Change MAC promiscuity and multicast hash at the same time
From: Steve Hodgson <shodgson@solarflare.com>
Currently we can set multicast hash immediately (in atomic context)
but must delay setting MAC promiscuity. There is not that much
point in deferring one but not the other, and setting the multicast
hash on Siena will involve a firmware request. So process them
both in efx_mac_work().
Also, set the broadcast bit in the multicast hash in
efx_set_multicast_list(), since this is required for both Falcon and
Siena.

sfc: Simplify XMAC link polling
From: Steve Hodgson <shodgson@solarflare.com>
Only the XMAC on Falcon needs help from the driver to poll and reset
the MAC-PHY link (XAUI); GMII is a simple parallel bus and on later
NICs firmware takes care of the XAUI link. Also, an XMAC interrupt
currently schedules a work item which simply clears a flag
(efx_nic::mac_up) to be checked by the regular monitor (or the next
link reconfiguration, if that is sooner).
Rename the flag to xmac_poll_required, changing its sense. Remove the
needless indirection and just set the flag immediately. Call
falcon_xmac_poll() directly where required.
Add a new generic operation mac_op::check_fault to check the link
outside of regular monitoring, as required during self-tests.
(Note that this leaves us with an unused work item, but we will
immediately have another use for it.)

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.

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

ipw2100: Register the wiphy device
libipw unconditionally calls wiphy_unregister, but it's up to the driver
to register it in the first place. ipw2100 fails to do so. Add the necessary
glue code, and also ensure that rfkill statuses get set up appropriately.

libipw: initiate cfg80211 API conversion (v2)
Initiate the conversion of libipw to the new cfg80211 configuration API.
For now, leave CONFIG_IPW2200_PROMISCUOUS stuff alone. Eventually
migrate it to cfg80211 when the add/del/change_virtual_intf methods
are implemented.
(v2: Fix unconditional wiphy_unregister in libipw which was causing
problems for ipw2100, somewhat based on prior attempted fix
by Zhu Yi <yi.zhu@intel.com>. Previously both original version of
this patch and Zhu Yi's fix attempt were reverted due to
discovery of regressions. -- JWL)

e1000e: update Tx Unit hang detection message
The Tx unit hang detection code in e1000e detects other hangs caused by
hardware components (e.g. Rx, DMA units), but it is not possible to detect
exactly which component is hung so it has always assumed a Tx unit hang.
When dumping a message to the system log because of a hang, this patch adds
more data to help narrow the cause of the issue and makes the message
non-Tx-specific. Because this new code reads PHY registers which can
sleep, move it off to a workqueue. This and all previously existing work
tasks in the driver are now cancelled when the driver is removed.
