Merge branch 'mlxsw-Make-driver-more-robust'
Ido Schimmel says: ==================== mlxsw: Make driver more robust In recent months we fixed several bugs in the driver that could have been avoided by re-evaluating some of the involved code paths and by introducing relevant and comprehensive test cases. This patchset tries to do that by introducing a set of small and mostly non-functional changes in addition to a new test. I have further improvements in mind, but they can be done in a different set. Patch #1 makes sure we correctly sanitize upper devices of a VLAN interface. Patch #2 removes an unexpected behavior from the driver, in which routes configured on a VLAN interface will cease being offloaded after certain operations. Patch #3 is a small cleanup. Patch #4 simplifies the driver by removing reference counting from VLAN entries configured on a port. Patches #5-#6 simplify linking/unlinking from a bridge, especially when LAG and VLAN devices are involved. They make both operations symmetric even when ports are unlinked from a bridged LAG device. Patch #7-#9 make router interface (RIF) deletion more robust by removing reliance on device chain to indicate whether a NETDEV_DOWN event in the inet{,6}addr notification chains should be processed. This is due to the fact that IP addresses can be flushed from a netdev after it was unlinked from its lower device. Patch #10 adds a new test to for valid and invalid configurations over mlxsw ports. Some of the test cases are derived from recent fixes. I expect that more test cases will be added over time. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
