[PATCH openEuler-22.03-LTS-SP1 5/6] bnxt_en: Implement .set_port / .unset_port UDP tunnel callbacks

From: Somnath Kotur <somnath.kotur(a)broadcom.com> stable inclusion from stable-v5.10.184 commit 3f6dfff5fe416bda6469cf235eaa9c54fee2a0bc category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8L4MY Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 1eb4ef12591348c440ac9d6efcf7521e73cf2b10 ] As per the new udp tunnel framework, drivers which need to know the details of a port entry (i.e. port type) when it gets deleted should use the .set_port / .unset_port callbacks. Implementing the current .udp_tunnel_sync callback would mean that the deleted tunnel port entry would be all zeros. This used to work on older firmware because it would not check the input when deleting a tunnel port. With newer firmware, the delete will now fail and subsequent tunnel port allocation will fail as a result.

If a default VLAN is enabled, the VF cannot support VLAN acceleration on the receive side and the VNIC must be setup to strip out the default VLAN tag. If a default VLAN is not enabled, the VF can support VLAN acceleration on the receive side. The VNIC should be set up to strip or not strip the VLAN based on the RX VLAN acceleration setting. Without this call to determine the default VLAN before calling bnxt_setup_vnic(), the VNIC may not be set up correctly. For example, bnxt_setup_vnic() may set up to strip the VLAN tag based on stale default VLAN information. If RX VLAN acceleration is not enabled, the VLAN tag will be incorrectly stripped and the RX data path will not work correctly.

From: Florian Fainelli <f.fainelli(a)gmail.com> stable inclusion from stable-v5.10.181 commit 43f6575004e0bbe0acc5d7a1955f326b22f38121 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8L4MY Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 225c657945c4a6307741cb3cc89467eadcc26e9b ] Removing the phy_stop() from bcmgenet_netif_stop() ended up causing warnings from the PHY library that phy_start() is called from the RUNNING state since we are no longer stopping the PHY state machine during bcmgenet_suspend(). Restore the call to phy_stop() but make it conditional on being called from the close or suspend path.

From: Florian Fainelli <f.fainelli(a)gmail.com> stable inclusion from stable-v5.10.181 commit e92727ed9e8b6798efc1e7ae44bbe7c44c453670 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8L4MY Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 93e0401e0fc0c54b0ac05b687cd135c2ac38187c ] The call to phy_stop() races with the later call to phy_disconnect(), resulting in concurrent phy_suspend() calls being run from different CPUs. The final call to phy_disconnect() ensures that the PHY is stopped and suspended, too.
