Using PPP networking under Linux

[PATCH v3 1/4] ppp: adds new decompressor error code to signal that packet must be dropped

From: "Jorge Boncompte [DTI2]" <jorge <at> dti2.net>

Currently decompressors can't signal the generic PPP layer to silently
drop a packet without notifying the PPP daemon or the other party.
