2020-04-28net: ethernet: fec: Prevent MII event after MII_SPEED writeAndrew Lunn
The change to polled IO for MDIO completion assumes that MII events are only generated for MDIO transactions. However on some SoCs writing to the MII_SPEED register can also trigger an MII event. As a result, the next MDIO read has a pending MII event, and immediately reads the data registers before it contains useful data. When the read does complete, another MII event is posted, which results in the next read also going wrong, and the cycle continues. By writing 0 to the MII_DATA register before writing to the speed register, this MII event for the MII_SPEED is suppressed, and polled IO works as expected.

Jakub Kicinski says: ==================== kselftest: add fixture parameters This set is an attempt to make running tests for different sets of data easier. The direct motivation is the tls test which we'd like to run for TLS 1.2 and TLS 1.3, but currently there is no easy way to invoke the same tests with different parameters. Tested all users of kselftest_harness.h. Dave, would it be possible to take these via net-next? It seems we're failing to get Shuah's attention. v2: - don't run tests by fixture - don't pass params as an explicit argument v3: - go back to the orginal implementation with an extra parameter, and running by fixture (Kees); - add LIST_APPEND helper (Kees); - add a dot between fixture and param name (Kees); - rename the params to variants (Tim); v4: - whitespace fixes. v5 (Kees): - move a comment; - remove a temporary variable; - reword the commit message on patch 4. v6: - resend for net-next. v1: https://lore.kernel.org/netdev/20200313031752.2332565-1-kuba@kernel.org/ v2: https://lore.kernel.org/netdev/20200314005501.2446494-1-kuba@kernel.org/ v3: https://lore.kernel.org/netdev/20200316225647.3129354-1-kuba@kernel.org/ v4: https://lore.kernel.org/netdev/20200317010419.3268916-1-kuba@kernel.org/ v5: https://lore.kernel.org/netdev/20200318010153.40797-1-kuba@kernel.org/ ==================== Signed-off-by: David S.

2020-04-28kselftest: add fixture variantsJakub Kicinski
Allow users to build parameterized variants of fixtures. If fixtures want variants, they call FIXTURE_VARIANT() to declare the structure to fill for each variant. Each fixture will be re-run for each of the variants defined by calling FIXTURE_VARIANT_ADD() with the differing parameters initializing the structure. Since tests are being re-run, additional initialization (steps, no_print) is also added.

Ido Schimmel says: ==================== mlxsw: Rework matchall offloading plumbing Jiri says: Currently the matchall and flower are handled by registering separate callbacks in mlxsw. That leads to faulty indication "in_hw_count 2" in filter show command for every inserted flower filter. That happens because matchall callback just blindly returns 0 for it and it is wrongly accounted for as "the offloader". I inspected different ways to fix this problem. The only clean solution is to rework handling of matchall in mlxsw a bit. The driver newely registers one callback for bound block which is called for both matchall and flower filter insertions. On the way, iron out the matchall code a bit, push it into a separate file etc. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
