NFSv4 introduce max_connect mount options
This option will control up to how many xprts can the client establish to the server with a distinct address (that means nconnect connections are not counted towards this new limit). This patch is setting up nfs structures to keeep track of the max_connect limit (does not enforce it). The default value is kept at 1 so that no current mounts that don't want any additional connections would be effected. The maximum value is set at 16. Mounts to DS are not limited to default value of 1 but instead set to the maximum default value of 16 (NFS_MAX_TRANSPORTS).
