[PATCH] uml: slirp and slip driver cleanups and fixes
This patch merges a lot of duplicated code in the slip and slirp drivers, abstracts out the slip protocol, and makes the slip driver work in 2.6. Signed-off-by: Jeff Dike <jdike@addtoit.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
