[PATCH net v3 0/2] net: ethernet: ti: am65-cpsw: Fixes to multi queue RX feature

Posted by Roger Quadros 3 weeks, 2 days ago

On J7 platforms, setting up multiple RX flows was failing
as the RX free descriptor ring 0 is shared among all flows
and we did not allocate enough elements in the RX free descriptor
ring 0 to accommodate for all RX flows. Patch 1 fixes this.

The second patch fixes a warning if there was any error in
am65_cpsw_nuss_init_rx_chns() and am65_cpsw_nuss_cleanup_rx_chns()
was called after that.
