It also lacks any error checking in the core. This certainly shows in the varying implementations across the drivers. Improve the documentation and add most basic checks. Sadly, it's probably too late now to try to enforce much more uniformity. Any thoughts & suggestions welcome. Next step is to add netlink for FEC, then stats. v2: - fix patch 5 - adjust kdoc in patches 3 and 6 Jakub Kicinski (6): ethtool: fec: fix typo in kdoc ethtool: fec: remove long structure description ethtool: fec: sanitize ethtool_fecparam->reserved ethtool: fec: sanitize ethtool_fecparam->active_fec ethtool: fec: sanitize ethtool_fecparam->fec ethtool: clarify the ethtool FEC interface include/uapi/linux/ethtool.h | 45 +++++++++++++++++++++++++++--------- net/ethtool/ioctl.c | 9 ++++++++ 2 files changed, 43 insertions(+), 11 deletions(-)
