Subject: [SCTP]: Annotate ->dst_saddr()
X-Git-Tag: v2.6.20-rc2~6^2~13^2~226
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=854d43a465cc8ba8e501320b3bc27359d909da2f;p=~emulex%2Finfiniband.git

[SCTP]: Annotate ->dst_saddr()

switched to taking a pointer to net-endian sctp_addr
and a net-endian port number.  Instances and callers
adjusted; interestingly enough, the only calls are
direct calls of specific instances - the method is not
used at all.
