Daniel Borkmann 3a461da1d0 cls_bpf: reset class and reuse major in da ... There are two issues with the current code. First one is that we need to set res->class to 0 in case we use non-default classid matching. This is important for the case where cls_bpf was initially set up with an optional binding to a default class with tcf_bind_filter(), where the underlying qdisc implements bind_tcf() that fills res->class and tests for it later on when doing the classification. Convention for these cases is that after tc_classify() was called, such qdiscs (atm, drr, qfq, cbq, hfsc, htb) first test class, and if 0, then they lookup based on classid. Second, there's a bug with da mode, where res->classid is only assigned a 16 bit minor, but it needs to expand to the full 32 bit major/minor combination instead, therefore we need to expand with the bound major. This is fine as classes belonging to a classful qdisc must share the same major.
