net: hibmcge: Add pauseparam supported in this module 

maillist inclusion
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/IBM1QO
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next.git/commit/?id=3a03763f3876



----------------------------------------------------------------------

The MAC can automatically send or respond to pause frames.
This patch supports the function of enabling pause frames
by using ethtool.
