Subject: [PATCH 3/8] [kernel] Remove send and recv default buffer values for
SCTP
After testing on Linux, FreeBSD and Solaris, these values (65536
for sndbuf and 1024 for recbuf) seemed unnecessary convservative.
Therefor, these default values for send (sndbuf) and recv (recbuf)
buffers for SCTP has been removed.
