Re: [PATCH net-next v2] net: mana: Cache MANA_QUERY_LINK_CONFIG result to avoid repeated HWC queries

Hello:

This patch was applied to netdev/net-next.git (main)

mana_query_link_cfg() sends an HWC command to firmware on every call,
but the link speed and QoS values it returns only change when the
driver explicitly calls mana_set_bw_clamp(). This function is called
not only by userspace via ethtool get_link_ksettings, but also
periodically by hv_netvsc through netvsc_get_link_ksettings and by
the sysfs speed_show attribute via dev_attr_show, resulting in
unnecessary HWC traffic every few minutes.
