When budget is non-zero, skb_unref() has already handled the NULL checking. When budget is zero, the dev_consume_skb_any() has handled NULL checking in __dev_kfree_skb_irq(), or dev_kfree_skb() which also ultimately call skb_unref(). So remove the unnecessary checking in napi_consume_skb(). Signed-off-by:

Dan Murphy says: ==================== 100base Fx link modes As per patch https://lore.kernel.org/patchwork/patch/1300241/ the link modes for 100base FX full and half duplex modes did not exist. Adding these link modes to the core and ethtool allow devices like the DP83822, DP83869 and Broadcomm PHYs to properly advertise the correct mode for Fiber 100Mbps. Corresponding user land ethtool patches are available but rely on these patches to be applied first. ==================== Signed-off-by:

Vladimir Oltean says: ==================== Felix DSA driver cleanup: build Seville separately When introducing the Seville switch support to the Felix driver, some technical debt was created. Since both VSC9959 and VSC9953 are embedded switches (one on an arm64 SoC and the other on a powerpc SoC), there is no use case for having the code for both be present in the same module. This was necessary at the time due to the common SERDES PCS code that they were using, but that has been since refactored into drivers/net/pcs/pcs-lynx.c. This makes the Seville driver stop uselessly depending upon PCI and FSL_ENETC_MDIO, which were only dependencies of Felix in fact. Some whitespace/tab conversions are also present in this series as part of the cleanup process. ==================== Signed-off-by: -

While we don't plan on making any changes to this function, currently this is the only remaining dependency between felix and seville, after the PCS has been refactored out into pcs-lynx.c. Duplicate this function in seville to break the dependency completely. Signed-off-by:

The overall idea (issue soft reset, enable memories, initialize memories, enable core) is the same, so it would make sense that an attempt is made to unify the procedures.
