Subject: [PATCH net-next 0/2] net: ti: icssg: Remove dedicated workqueue
 for ndo_set_rx_mode callback

While addressing an issue in the cpsw driver, I based my fix on the
implementation of the emac_ndo_set_rx_mode() function in icssg. During review,
Jakub pointed out that the dedicated workqueue for the ndo_set_rx_mode
callback might be unnecessary. I subsequently used the system workqueue for
this purpose in the cpsw driver, and it performed as expected. Therefore,
I believe the same approach can be applied to the icssg driver. These two
patches aim to remove this dedicated workqueue for icssg drivers.

Please note: I do not have access to a board that supports the CSSG PRU
Ethernet controller, so this change has only been build-tested.
