e1000e: 82579 jumbo frame workaround causing CRC errors
The subject workaround was causing CRC errors due to writing the wrong register with updates of the RCTL register. It was also found that the workaround function which modifies the RCTL register was being called in the middle of a read-modify-write operation of the RCTL register, so the function call has been moved appropriately. Lastly, jumbo frames must not be allowed when CRC stripping is disabled by a module parameter because the workaround requires the CRC be stripped.
