Originally it was thought there were issues with ICHx/PCH parts with packet
split when jumbo frames were enabled but in fact it is really only when
early-receive is enabled (via ERT register) on these parts. Use packet
split with jumbos but only when early-receive is not enabled.

when resetting the part since it is on page 800 (and will be cleared on
