net: phy: fix write to mii-ctrl1000 register

2019-10-29T08:21:45Z

[ Upstream commit 4cf6c57e61fee954f7b7685de31b80ec26843d27 ] When userspace writes to the MII_ADVERTISE register, we update phylib's advertising mask and trigger a renegotiation. However, writing to the MII_CTRL1000 register, which contains the gigabit advertisement, does neither. This can lead to phylib's copy of the advertisement becoming de-synced with the values in the PHY register set, which can result in incorrect negotiation resolution.

net: mii: Fix PAUSE cap advertisement from linkmode_adv_to_lcl_adv_t() helper

2019-03-28T05:49:06Z

With a recent link mode advertisement code update this helper providing local pause capability translation used for flow control link mode negotiation got broken. For eth drivers using this helper, the issue is apparent only if either PAUSE or ASYM_PAUSE is being advertised.

2018-12-06T00:26:16Z

Rename mii_stat1000_to_linkmode_lpa_t to mii_stat1000_mod_linkmode_lpa_t to indicate it modifies the passed linkmode bitmap, without clearing any other bits. Add a helper to set/clear bits in a linkmode. Use this helper to ensure bit are clear which the stat1000 indicates should not be set.

net: ethernet: Convert phydev advertize and supported from u32 to link mode

2018-11-11T18:10:01Z

There are a few MAC/PHYs combinations which now support > 1Gbps. These may need to make use of link modes with bits > 31. Thus their supported PHY features or advertised features cannot be implemented using the current bitmap in a u32. Convert to using a linkmode bitmap, which can support all the currently devices link modes, and is future proof as more modes are added. Signed-off-by: Andrew Lunn Signed-off-by: David S. Miller
