Xiaotian Feng 984a4a0378 staging: ozwpan: use tasklet_kill in device remove/release process
Some driver uses tasklet_disable in device remove/release process,
tasklet_disable will inc tasklet->count and return. If the tasklet
is not handled yet under some softirq pressure, the tasklet will be
placed on the tasklet_vec, never have a chance to be excuted. This might
lead to a heavy loaded ksoftirqd, wakeup with pending_softirq, but
tasklet is disabled. tasklet_kill should be used in this case.

Tomas Winkler 07732be2ef staging: ozwpan: fix memcmp() test in oz_set_active_pd()
"addr" is a pointer so it's either 4 or 8 bytes, but actually we want
to compare 6 bytes (ETH_ALEN).

As network stack already provides helper function
is_zero_ether_addr() we use that instead of memcmp
