-Subject: [PATCH] PPP: When un-escaping, don't allocate a too-large buffer.
-
-The buffer should be big enough to hold the captured data, but it
-doesn't need to be big enough to hold the entire on-the-network packet,
-if we haven't captured all of it.
-
-(backported from commit e4add0b010ed6f2180dcb05a13026242ed935334)
