We have tools/testing/selftests/drivers/net/gro.c and associated Python
test. (note I have ambiguous feelings about adding ppp cases to this
file vs creating a new test, adding Willem to CC maybe he has some
guidance)
The test itself should send and receive raw packets using packet
sockets. That way you can easily inject arbitrary fragmented frames
on one end and check if they are coalesced correctly on the other.
