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

2019-03-28T05:49:06+00:00

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.

Add a _mod_ variant of mii_lpa_to_linkmode_lpa_t. Use this to fix the
genphy_read_status() where the 1G link partner features are getting
lost.

net: mii: Rename mii_stat1000_to_linkmode_lpa_t

2018-12-06T00:26:16+00:00

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: mii: Fix autoneg in mii_lpa_to_linkmode_lpa_t()

2018-12-06T00:26:16+00:00

mii_adv_to_linkmode_adv_t() clears all bits before setting it needs to
set. This means the freshly set Autoneg gets cleared.

Change the order, and add comments about it clearing the old content
of the bitmap.

Convert phy drivers to report the link partner advertised modes using
a linkmode bitmap. This allows them to report the higher speeds which
don't fit in a u32.

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

2018-11-11T18:10:01+00:00

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.
