linux-toradex.git/Documentation/networking/ethtool-netlink.rst, branch v5.15-rc2 Linux kernel for Apalis and Colibri modules ethtool: add two coalesce attributes for CQE mode 2021-08-24T14:38:28+00:00 Yufeng Mo moyufeng@huawei.com 2021-08-20T07:35:17+00:00 029ee6b14356b94120bedb852dcdaefc0a282cf1 Currently, there are many drivers who support CQE mode configuration, some configure it as a fixed when initialized, some provide an interface to change it by ethtool private flags. In order to make it more generic, add two new 'ETHTOOL_A_COALESCE_USE_CQE_TX' and 'ETHTOOL_A_COALESCE_USE_CQE_RX' coalesce attributes, then these parameters can be accessed by ethtool netlink coalesce uAPI. Also add an new structure kernel_ethtool_coalesce, then the new parameter can be added into this struct.

The IEEE standard mandates two sets of counters: - 30.5.1.1.17 aFECCorrectedBlocks - 30.5.1.1.18 aFECUncorrectableBlocks where block is a block of bits FEC operates on. Each of these counters is defined per lane (PCS instance). Multiple vendors provide number of corrected _bits_ rather than/as well as blocks. This set adds the 2 standard-based block counters and a extra one for corrected bits. Counters are exposed to user space via netlink in new attributes. Each attribute carries an array of u64s, first element is the total count, and the following ones are a per-lane break down. Much like with pause stats the operation will not fail when driver does not implement the get_fec_stats callback (nor can the driver fail the operation by returning an error). If stats can't be reported the relevant attributes will be empty. Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>
