FC Mgmt mib - buffer credit objects

[Arvind Prabhudev <arvindp@cisco.com>]

Hello Keith,

Fibre Channel Management MIB: draft-ietf-ips-fcmgmt-mib-02

I had a comment about fcmFLoginBbCredit & fcmISPortClassFCredit objects.
Since, it is possible to have an implementation where the buffer credit is
configurable, I would suggest that we make these 2 objects read-write now
rather than having to deprecate these and create new objects in the
future. We could add a MIN-ACCESS clause of read-only for both these
objects.

thanks,
Arvind
