qlge: Add support for getting/setting port config.

This patch adds functionality to get and set port parameters.
Currently it is used to set maximum TX/RX frame sizes. This process is
also capable of setting:
1) Pause type: Standard or Priority based.
2) Loop back mode.
3) Enable Jumbo frame mode (included here...)
