tg3: Assign correct tx margin for 5719
Commit d309a46e42542223946d3a9e4e239fdc945cb53e, entitled "tg3: 5719: Prevent tx data corruption", was supposed to contain the tx margin adjustment but it looks like it somehow was omitted. This patch fixes the problem. Signed-off-by: Matt Carlson <mcarlson@broadcom.com> Reviewed-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
