Vladimir Oltean 9d5ef190e5 net: dsa: automatically bring up DSA master when opening user port ... DSA wants the master interface to be open before the user port is due to historical reasons. The promiscuity of interfaces that are down used to have issues, as referenced Lennert Buytenhek in commit df02c6ff2e ("dsa: fix master interface allmulti/promisc handling"). The bugfix mentioned there, commit b6c40d68ff ("net: only invoke dev->change_rx_flags when device is UP"), was basically a "don't do that" approach to working around the promiscuity while down issue. Further work done by Vlad Yasevich in commit d2615bf450 ("net: core: Always propagate flag changes to interfaces") has resolved the underlying issue, and it is strictly up to the DSA and 8021q drivers now, it is no longer mandated by the networking core that the master interface must be up when changing its promiscuity. From DSA's point of view, deciding to error out in dsa_slave_open because the master isn't up is (a) a bad user experience and (b) knocking at an open door. Even if there still was an issue with promiscuity while down, DSA could still just open the master and avoid it. Doing it this way has the additional benefit that user space can now remove DSA-specific workarounds, like systemd-networkd with BindCarrier: https://github.com/systemd/systemd/issues/7478 And we can finally remove one of the 2 bullets in the "Common pitfalls using DSA setups" chapter. Tested with two cascaded DSA switches: $ ip link set sw0p2 up fsl_enetc 0000:00:00.2 eno2: configuring for fixed/internal link mode fsl_enetc 0000:00:00.2 eno2: Link is Up - 1Gbps/Full - flow control rx/tx mscc_felix 0000:00:00.5 swp0: configuring for fixed/sgmii link mode mscc_felix 0000:00:00.5 swp0: Link is Up - 1Gbps/Full - flow control off 8021q: adding VLAN 0 to HW filter on device swp0 sja1105 spi2.0 sw0p2: configuring for phy/rgmii-id link mode IPv6: ADDRCONF(NETDEV_CHANGE): eno2: link becomes ready IPv6: ADDRCONF(NETDEV_CHANGE): swp0: link becomes ready Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>		2021-02-06 14:42:57 -08:00
