sctp: do trace_sctp_probe after SACK validation and check
The function sctp_sf_eat_sack_6_2 now performs the Verification
Tag validation, Chunk length validation, Bogu check, and also
the detection of out-of-order SACK based on the RFC2960
Section 6.2 at the beginning, and finally performs the further
processing of SACK. The trace_sctp_probe now triggered before
the above necessary validation and check.
this patch is to do the trace_sctp_probe after the chunk sanity
tests, but keep doing trace if the SACK received is out of order,
for the out-of-order SACK is valuable to congestion control
debugging.
v1->v2:
- keep doing SCTP trace if the SACK is out of order as Marcelo's
suggestion.
v2->v3:
- regenerate the patch as v2 generated on top of v1, and add
'net-next' tag to the new one as Marcelo's comments.
