[TG3]: Disable TSO on 5906 if CLKREQ is enabled.
Due to hardware errata, TSO must be disabled if the PCI Express clock request is enabled on 5906. The chip may hang when transmitting TSO frames if CLKREQ is enabled. Update version to 3.69. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
