Updates for the Mellanox ethernet driver

Browse Source 
> List of fixes:
  * use correct format for GID printouts
  * double array indexing
  * spelling in printouts
  * void pointer arithmetic
  * allow more receive rings
  * correct maximum number of transmit rings
  * use "const" instead of "static" for constants
  * check for invalid VLAN tags
  * check for lack of IRQ resources
> Added more hardware specific defines
> Added more verbose printouts of firmware status codes
