BCM/mips still hang up

Wed Nov 14 07:46:36 UTC 2018

Hi Hiroki-san,

Blame on me... I have buggy code of network driver, so I don't want to
commit it into tree. On TX path it free buffer for each interrupt call. But
not each TX packet causes interrupt, so I need to fix post-TX cleanup
function to free all mbuf until current descriptor.
In addition, I'm not sure it's last bug ;)

Thx!
