[TG3]: Workaround 5752 A0 chip ID
The 5752 A0 chip ID is wrong in hardware. The simplest way to workaround it is to change it to the correct value in tp->pci_chip_rev_id. This way, it is easier to check for the ASIC_REV_5752 in the rest of the driver. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
