Subject: [PATCH 1/2] [PATCH] Send wireless netlink events with a clean slate

Drivers expect to be able to call wireless_send_event in arbitrary
contexts.  On the other hand, netlink really doesn't like being
invoked in an IRQ context.  So we need to postpone the sending of
netlink skb's to a tasklet.

Subject: [PATCH 2/2] [PATCH] myri10ge: always re-enable dummy rdmas in
 myri10ge_resume

Dummy RDMA are always enabled on device startup since commit
9a71db721a2cbb9921b929b2699ab181f5a3c6c0 (to work around buggy
PCIe chipsets which do not implement resending properly). But,
we also need to always re-enable them when resuming the device.
