Subject: [PATCH net-next 1/6] tg3: Add new FW_TSO flag
From: Matt Carlson <mcarlson@...adcom.com>
tg3 used the fw_needed member loosely as a synonym for firmware TSO. Now
that the 57766 needs firmware download support, fw_needed can no longer be
used like this. This patch creates a new FW_TSO flag and changes the
code to use it.
Also rearrange all the TSO flags together in the enum.
