net/smc: allow sysctl rmem and wmem defaults for servers
Without setsockopt SO_SNDBUF and SO_RCVBUF settings, the sysctl defaults net.ipv4.tcp_wmem and net.ipv4.tcp_rmem should be the base for the sizes of the SMC sndbuf and rcvbuf. Any TCP buffer size optimizations for servers should be ignored. Signed-off-by: Ursula Braun <ubraun@linux.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
