Subject: [PATCH 78/82] net: sparx5: activate FDMA tx in start()
|
|
|
|
The function sparx5_fdma_tx_activate() is responsible for configuring
|
|
the TX FDMA instance and activating the channel. TX activation has
|
|
previously been done in the xmit() function, when the first frame is
|
|
transmitted. Now that we have separate functions for starting and
|
|
stopping the FDMA, it seems reasonable to move the TX activation to the
|
|
start function. This change has no implications on the functionality.
