net: txgbe: expend SW-FW mailbox buffer size to identify QSFP module 



Recent firmware updates introduce additional fields in the mailbox message
to provide more information for identifying 40G and 100G QSFP modules.
To accommodate these new fields, expand the mailbox buffer size by 4 bytes.

Without this change, drivers built against the updated firmware cannot
properly identify modules due to mismatched mailbox message lengths.

The old firmware version that used the smaller mailbox buffer has never
been publicly released, so there are no backward-compatibility concerns.
