net: stmmac: set TxQ mode back to DCB after disabling CBS
[ Upstream commit f317e2ea8c88737aa36228167b2292baef3f0430 ]
When disable CBS, mode_to_use parameter is not updated even the operation
mode of Tx Queue is changed to Data Centre Bridging (DCB). Therefore,
when tc_setup_cbs() function is called to re-enable CBS, the operation
mode of Tx Queue remains at DCB, which causing CBS fails to work.
This patch updates the value of mode_to_use parameter to MTL_QUEUE_DCB
after operation mode of Tx Queue is changed to DCB in stmmac_dma_qmode()
callback function.
Fixes: 1f705bc61aee ("net: stmmac: Add support for CBS QDISC")
