    e1000e: swap max hw supported frame size between 82574 and 82583
    
    There appears to have been a mixup in the max supported jumbo frame size
    between 82574 and 82583 which ended up disabling jumbo frames on the 82574
    as a result.  This patch swaps the two so that this issue is resolved.
