[PATCH net 3/5] net/mlx5e: remove IEEE/CEE mode check when setting DCBX mode

From: Huy Nguyen Currently, the function setdcbx fails if the request dcbx mode is either IEEE or CEE. We remove the IEEE/CEE mode check because we support both IEEE and CEE interfaces. Fixes: 3a6a931dfb8e ("net/mlx5e: Support DCBX CEE API") Signed-off-by: Huy Nguyen

[PATCH net 5/5] net/mlx5e: Fix loopback selftest

From: Eugenia Emantayev Change packet type handler to ETH_P_IP instead of ETH_P_ALL since we are already expecting an IP packet. Also, using ETH_P_ALL will cause the loopback test packet type handler to be called on all outgoing packets, especially our own self loopback

[PATCH net 2/5] net/mlx5: Don't save PCI state when PCI error is detected

From: Daniel Jurgens When a PCI error is detected the PCI state could be corrupt, don't save it in that flow. Save the state after initialization. After restoring the PCI state during slot reset save it again, restoring the state destroys the previously saved state info.

[PATCH net 4/5] net/mlx5e: Avoid wrong identification of rules on deletion

From: Or Gerlitz When deleting offloaded TC flows, we must correctly identify E-switch rules. The current check could get us wrong w.r.t to rules set on the PF. Since it's possible to set NIC rules on the PF, switch to SRIOV offloads mode and then attempt to delete a NIC

[PATCH] Make IP 'forwarding' doc more precise

It wasn't clear if the 'forwarding' setting needs to be enabled on the interface that packets are received from, or on the interface that packets are forwarded to, or both. In fact (according to my code reading) the setting is relevant on the interface that packets are received from, so this
