AQR115c reports incorrect PMA capabilities which includes 10G/5G and also incorrectly disables capabilities like autoneg and 10Mbps support. AQR115c as per the Marvell databook supports speeds up to 2.5Gbps with autonegotiation. Fixes: 0ebc581f8a4b ("net: phy: aquantia: add support for aqr115c") Link: https://lore.kernel.org/all/20240913011635.1286027-1-quic_abchauha@quicinc.com/T/ Signed-off-by: Abhishek Chauhan <quic_abchauha@quicinc.com> --- Changes since v5 1. Minor comments addressed such as having unsigned long *supported = phydev->supported; 2. Updated comments as per Russell suggestion. Changes since v4 1. Forget about asking hardware for PMA capabilites. 2. Just set the Gbits features along with 2.5Gbps support for AQR115c Phy chip. Changes since v3 1. remove setting of 2500baseX bit introduced as part of previous patches. 2. follow reverse xmas declaration of variables. 3. remove local mask introduced as part of previous patch and optimize the logic. Changes since v2 1. seperate out the changes into two different patches. 2. use phy_gbit_features instead of initializing each and every link mode bits. 3. write seperate functions for 2.5Gbps supported phy. 4. remove FIBRE bit which was introduced in patch 1. Changes since v1 1. remove usage of phy_set_max_speed in the aquantia driver code. 2. Introduce aqr_custom_get_feature which checks for the phy id and takes necessary actions based on max_speed supported by the phy. 3. remove aqr111_config_init as it is just a wrapper function. drivers/net/phy/aquantia/aquantia_main.c | 14 ++++++++++++++ 1 file changed, 14 insertions(+)
