Description Andrew Korovin 2005-02-04 23:20:17 UTC 
After pppd establishes connection, if "options MAC" is enabled in the kernel, kernel panic happens.

Fix: 

Unknown.
How-To-Repeat: To repeat the problem, you'll have to Enable "options MAC" in kernel and call your ISP with pppd.

Hello,
I'm not able to test it in working environment right now, but attached patch
should correct this problem. Needs testing. The problem is that
mac_check_ifnet_transmit() needs to have packet header in passed mbuf. This
function is called from: pppwrite() -- pppoutput() --
mac_check_ifnet_transmit(). Attached patch should correct this problem.
