smsc95xx: Configure pause time to 0xffff when tx flow control enabled

commit 9c0827317f235865ae421293f8aecf6cb327a63e upstream.

Configure pause time to 0xffff when tx flow control enabled

Set pause time to 0xffff in the pause frame to indicate the
partner to stop sending the packets. When RX buffer frees up,
the device sends pause frame with pause time zero for partner to
resume transmission.
