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...)
