Subject: ethtool: update mapping of features to legacy ioctl requests
Patch-mainline: v5.7-rc1
Git-commit: f70bb06563ed07e4ba064f2785dba0bef96cd449
References: bsc#1176447
Legacy ioctl request like ETHTOOL_GTXCSUM are still used by ethtool utility
to get values of legacy flags (which rather work as feature groups). These
are calculated from values of actual features and request to set them is
implemented as an attempt to set all features mapping to them but there are
two inconsistencies:
- tx-checksum-fcoe-crc is shown under tx-checksumming but NETIF_F_FCOE_CRC
is not included in ETHTOOL_GTXCSUM/ETHTOOL_STXCSUM
- tx-scatter-gather-fraglist is shown under scatter-gather but
NETIF_F_FRAGLIST is not included in ETHTOOL_GSG/ETHTOOL_SSG
As the mapping in ethtool output is more correct from logical point of
view, fix ethtool_get_feature_mask() to match it.
