ethtool: Fix get module eeprom fallback

2022-06-18T03:22:16Z

Function fallback_set_params() checks if the module type returned by a driver is ETH_MODULE_SFF_8079 and in this case it assumes that buffer returns a concatenated content of page A0h and A2h. The check is wrong because the correct type is ETH_MODULE_SFF_8472.

ethtool: Fix and simplify ethtool_convert_link_mode_to_legacy_u32()

2022-06-14T06:11:35Z

Fix the implementation of ethtool_convert_link_mode_to_legacy_u32(), which is supposed to return false if src has bits higher than 31 set. The current implementation uses the complement of bitmap_fill(ext, 32) to test high bits of src, which is wrong as bitmap_fill() fills _with long granularity_, and sizeof(long) can be > 4. No users of this function currently check the return value, so the bug was dormant. Also remove the check for __ETHTOOL_LINK_MODE_MASK_NBITS > 32, as the enum ethtool_link_mode_bit_indices contains far beyond 32 values. Using find_next_bit() to test the src bitmask works regardless of this anyway.

net: rename reference+tracking helpers

2022-06-10T04:52:55Z

Netdev reference helpers have a dev_ prefix for historic reasons. Renaming the old helpers would be too much churn but we can rename the tracking ones which are relatively recent and should be the default for new code. Rename: dev_hold_track() -> netdev_hold() dev_put_track() -> netdev_put() dev_replace_track() -> netdev_ref_replace() Link: https://lore.kernel.org/r/20220608043955.919359-1-kuba@kernel.org Signed-off-by: Jakub Kicinski

net: ethtool: move checks before rtnl_lock() in ethnl_set_rings

2022-04-15T18:41:45Z

Currently these two checks in ethnl_set_rings are added after rtnl_lock() which will do useless works if the request is invalid. So this patch moves these checks before the rtnl_lock() to avoid these costs. Signed-off-by: Jie Wang Signed-off-by: Guangbin Huang Signed-off-by: Jakub Kicinski

net: ethtool: extend ringparam set/get APIs for tx_push

2022-04-15T18:41:35Z

Currently tx push is a standard driver feature which controls use of a fast path descriptor push. So this patch extends the ringparam APIs and data structures to support set/get tx push by ethtool -G/g. Signed-off-by: Jie Wang Signed-off-by: Guangbin Huang Signed-off-by: Jakub Kicinski

ethtool: add header/data split indication

2022-01-28T14:43:47Z

For applications running on a mix of platforms it's useful to have a clear indication whether host's NIC supports the geometry requirements of TCP zero-copy. TCP zero-copy Rx requires data to be neatly placed into memory pages. Most NICs can't do that. This patch is adding GET support only, since the NICs I work with either always have the feature enabled or enable it whenever MTU is set to jumbo. In other words I don't need SET. But adding set should be trivial. (The only note on SET is that we will likely want the setting to be "sticky" and use 0 / `unknown` to reset it back to driver default.)
