transfer data and throw some errors in these conditions:
1 . mount nfs via wireless network,if i transfer a lot of data.it may stop
receiving data after some time.
2 . wireless network is busy, then some one reboot the wireless AP.it may
throw some errors and stop working.
3 . Find wireless network works slow and switch to Ethernet,.if  try
/etc/rc.d/netif restart, it may throw some errors and stop working.


all these are fixed by reboot system(reload iwn and iwnfw  dose not work at
most time). i also find iwn driver printe a lot of microcode error related
messages when it failed(not easy to reproduce it).

No official Change Log, i just notice the *description *in gentoo
bug#202818.
