The method ndo_start_xmit() is defined as returning an 'netdev_tx_t',
which is a typedef for an enum type, so make sure the implementation in
this driver has returns 'netdev_tx_t' value, and change the function
return type to netdev_tx_t.

[ Upstream commit 75a110a1783ef8324ffd763b24f4ac268253cbca ]

This is a workaround for FW bug -
MFW generates bandwidth attention in single function mode, which
is only expected to be generated in multi function mode.
This undesired attention in SF mode results in incorrect HW
configuration and resulting into Tx timeout.

[ Upstream commit 2b49117a5abee8478b0470cba46ac74f93b4a479 ]

The method ndo_start_xmit() is defined as returning an 'netdev_tx_t',
which is a typedef for an enum type, so make sure the implementation in
this driver has returns 'netdev_tx_t' value, and change the function
return type to netdev_tx_t.

[ Upstream commit a5c3021bb62b970713550db3f7fd08aa70665d7e ]

If the remote is not able to fully utilize the MPS choosen recalculate
the credits based on the actual amount it is sending that way it can
still send packets of MTU size without credits dropping to 0.
