Patch 1 fixes a regression introduced in 6.4 where the MTU size could be
bigger than 'lmax'.

Patch 3 fixes an issue where the code doesn't account for qdisc_pkt_len()
returning a size bigger then 'lmax'.

Patches 2 and 4 are selftests for the issues above.

v2 -> v3:
 - Added Eric tags
 - Addressed issue in patch 4 pointed by Shaozheng

v1 -> v2:
 - Added another fix and selftest for sch_qfq
 - Addressed comment by Simon
 - Added Jamal acks and Shaozheng tested by
