unsigned int fc_peer::usage

Active usage count.

A peer (and attached ULPs) may be created in response to unsolicited login requests received via the fabric. We track our own active usage count independently of the existence of the peer, so that if the peer becomes logged out (e.g. due to a link failure) then we know whether or not we should attempt to relogin.
