This patch introduces /proc/net/smc4 and /proc/net/smc6 files to report
statistic information of SMC connections.
Compared with 'smcss' command in smc-tools, getting SMC connections via
proc files is not efficient. However, in some container scenarios, some
dependencies are lacked for compiling and using smc-tools. In this case,
using proc files to check SMC connections becomes a simple and fast way.

Hi Wen,
I can understand your problem and frustration. However, there are two
reasons I'm not really convinced by the proc file method:
1) AFAI, the proc method could consume many CPU time especially in case
with a log of sockets to read the pseudo files.
2) We have already implemented the complex netlink method on the same
purpose. I see the double expense to main the code.
Then the question is if the lack of dependency issue can be handle
somehow, or the proc method is the only way to achieve this purpose?
Any opinion is welcome!
Thanks,
Wenjia
