Do you do TX when this error appears? If yes, it's probably the XSKICOSQ
overflow issue fixed recently by this patch:
https://patchwork.ozlabs.org/project/netdev/patch/20200420213606.44292-4-saeedm@mellanox.com/
Though it looks like you run kernel 5.7.2 with the upstream driver
(right?), which should have this fix. Could you please verify that your
driver does indeed have this patch? If yes, and it still happens, we'll
have to reproduce and debug it.
Thanks,
Max
