[PATCH net-next v2 04/11] net: dsa: qca8k: do not cache unneeded EEE fields

The qca8k driver is currently caching a bitfield of the supported member of a ethtool_eee private structure, which is unused. Only the eee_enabled field of the private ethtool_eee copy is updated, thus using p->advertised and p->lp_advertised is also erroneous. Remove the usage of these private e

[PATCH net-next v2 06/11] net: dsa: bcm_sf2: remove unneeded supported flags
