This patch introduces kexec support for mlx5. When switching kernels, kexec() calls shutdown, which unloads the driver and cleans its resources. In addition, remove unregister netdev from shutdown flow. This will allow a clean shutdown, even if some netdev clients did not release their reference from this netdev. Releasing The HW resources only is enough as the kernel is shutting down Signed-off-by: NMajd Dibbiny <majd@mellanox.com> Signed-off-by: NTariq Toukan <tariqt@mellanox.com> Signed-off-by: NHaggai Abramovsky <hagaya@mellanox.com> Signed-off-by: NSaeed Mahameed <saeedm@mellanox.com> Signed-off-by: NDavid S.

Set and report vport MTU rather than physical MTU, Driver will set both vport and physical port mtu and will rely on the query of vport mtu. SRIOV VFs have to report their MTU to their vport manager (PF), and this will allow them to work with any MTU they need without failing the request. Also for some cases where the PF is not a port owner, PF can work with MTU less than the physical port mtu if set physical port mtu didn't take effect.

Avoid double mapping of io mapped memory, Device page may be mapped to non-cached(NC) or to write-combining(WC). The code before this fix tries to map it both to WC and NC contrary to what stated in Intel's software developer manual. Here we remove the global WC mapping of all UARS "dev->priv.bf_mapping", since UAR mapping should be decided per UAR (e.g we want different mappings for EQs, CQs vs QPs).

Support the ndo_setup_tc callback and the needed methods for multi TC/UP support, and removed the default_vlan_prio from mlx5e_priv which is always 0, it was replaced with hardcoded "0" in the new select queue method. For that we now create MAX_NUM_TC num of TISs (one per prio) on netdevice creation instead of priv->params.num_tc which was always 1. So far each channel had a single TXQ, Now each channel has a TXQ per TC (Traffic Class). Added en_dcbnl.c which implements the set/get DCBNL IEEE ETS, set/get dcbx and registers the mlx5e dcbnl ops. We still use the kernel's default TXQ selection method to select the channel to transmit through but now we use our own method to select the TXQ inside the channel based on VLAN priority. In mlx5, as opposed to mlx4, tc group N gets lower priority than tc group N+1.

NAPI drivers no longer need to observe a particular protocol to benefit from busy polling (CONFIG_NET_RX_BUSY_POLL=y) napi_hash_add() and napi_hash_del() are automatically called from core networking stack, respectively from netif_napi_add() and netif_napi_del() This patch depends on free_netdev() and netif_napi_del() being called from process context, which seems to be the norm. Drivers might still prefer to call napi_hash_del() on their own, since they might combine all the rcu grace periods into a single one, knowing their NAPI structures lifetime, while core networking stack has no idea of a possible combining. Once this patch proves to not bring serious regressions, we will cleanup drivers to either remove napi_hash_del() or provide appropriate rcu grace periods combining.

Prevent outgoing multicast frames from looping back to the RX queue. By introducing new HW capability self_lb_en_modifiable, which indicates the support to modify self_lb_en bit in modify_tir command. When this capability is set we can prevent TIRs from sending back loopback multicast traffic to their own RQs, by "refreshing TIRs" with modify_tir command, on every time new channels (SQs/RQs) are created at device open. This is needed since TIRs are static and only allocated once on driver load, and the loopback decision is under their responsibility. Fixes issues of the kind: "IPv6: eth2: IPv6 duplicate address fe80::e61d:2dff:fe5c:f2e9 detected!" The issue is seen since the IPv6 solicitations multicast messages are loopedback and the network stack thinks they are coming from another host.
