[PATCH net-next 04/15] bnxt_en: Do not include ETH_FCS_LEN in the max packet length sent to fw.

[Michael Chan]

From: Vasundhara Volam <vasundhara-v.vo...@broadcom.com>

The firmware does not expect the CRC to be included in the length
passed from the driver.  The firmware always configures the chip
to strip out the CRC.
