dev_mc_upload() from net/core/dev_mcast.c does

which calls myri10ge_change_promisc

which calls myri10ge_send_cmd

Hmm, if that is the only path where you call it, it may be
helpful to change myri10ge_change_promisc to call a special
atomic version of myri10ge_send_cmd then, while all others
use the regular version, which you can then convert to
do msleep as well.
