Adding support for BCM8727 - a dual port SFP+ PHY. That includes verification of
the optic module vendor and part number - the list of approved modules resides
on the nvram and the module is verified by the FW. Since not all users would
like to use this verification feature, it can be disabled. The default behavior
is to issue a warning if the module is not approved, but still allow using it -
but it is also possible to disable the link if the module is not approved.

E100 places it's RX packet descriptors inside skb->data and uses them
with bidirectional streaming DMA mapping. Unfortunately it fails to
transfer skb->data ownership to the device after it reads the
descriptor's status, breaking on non-coherent (e.g., ARM) platforms.

This have to be converted to use coherent memory for the descriptors.

Bonding device forbids slave device of different types under the same
master.

However, it is possible for a bonding master to change type during its
lifetime.  This can be either from ARPHRD_ETHER to ARPHRD_INFINIBAND
or the other way arround.  The change of type requires device level
multicast address cleanup because device level multicast addresses
depend on the device type.

The patch adds a call to dev_close() before the bonding master changes
type and dev_open() just after that.

In the example below I enslaved an IPoIB device (ib0) under
bond0. Since each bonding master starts as device of type ARPHRD_ETHER
by default, a change of type occurs when ib0 is enslaved.

This is how /proc/net/dev_mcast looks like without the patch

5    bond0           1     0     00ffffffff12601bffff000000000001ff96ca05

mkiss: ax0: Trying crc-smack
mkiss: ax0: Trying crc-flexnet

The issue was, that the locking code in mkiss was assuming it was only
ever being called in process or bh context.  Fixed by converting the
involved locking code to use irq-safe locks.

Review of other networking line disciplines shows that 6pack, both sync
and async PPP and STRIP have similar issues.  The ppp_async one is the
most interesting one as it sorts out half of the issue as far back as
2004 in commit http://git.kernel.org/?p=linux/kernel/git/tglx/history.git;a=commitdiff;h=2996d8deaeddd01820691a872550dc0cfba0c37dSigned-off-by: NRalf Baechle <ralf@linux-mips.org>

AD_STATE_LACP_ACTIVITY better reflects the intended semantics.

should be set here in accordance with 802.3ad 43.4.12; AD_SHORT_TIMEOUT
