SubjectRe: [PATCH] ppp_generic causes skput:under: w/ pppoatm and vc-encaps
   From: Till Immanuel Patzschke <>
Date: Tue, 13 Nov 2001 22:30:24 +0100

I've attached a patch, checking for headroom first, and - if necessary -
reallocating a larger buffer for the skb_push.

Please check and apply - or find a better fix!

Here is my "better fix". In pppoatm, we should be increasing the
device header length appropriately. ie. dev->hard_header_len needs to
be increased in the pppoatm driver when vc-encaps is used.

Franks a lot,
