Subject: [PATCH net-next v4 0/3] net: ethernet: cortina: Use phylib for RX
 and TX pause

This patch series switches the Cortina Gemini ethernet
driver to use phylib to set up RX and TX pause for the
PHY.

Signed-off-by: Linus Walleij <linus.walleij@...aro.org>

Changes in v4:
- Drop the register setting in .set_pauseparam(), just call
  phylib and let .adjust_link() handle this.
- Link to v3: https://lore.kernel.org/r/20240513-gemini-ethernet-fix-tso-v3-0-b442540cc140@linaro.org

Changes in v3:
- Do the pause setting unconditionally in the full duplex
  case in adjust_link just like the code used to be,
  phydev->autoneg should not influence this.
- Bail out of .set_pauseparam() if pparam->autoneg is not
  true.
- Link to v2: https://lore.kernel.org/r/20240511-gemini-ethernet-fix-tso-v2-0-2ed841574624@linaro.org

Changes in v2:
- Add a new patch to rename the gmac_adjust_link callback to
  a recognized name.
- Add a new patch to make the driver use the autonegitiated
  RX and TX pause settings from phylib.
- Rewrite the set_pauseparam() patch to use the existing
  gmac_set_flow_control() function.
- Add a call to phy_set_asym_pause() in the set_pauseparam
  callback, so the phylib is informed of the new TX/RX setting.
- Link to v1: https://lore.kernel.org/r/20240509-gemini-ethernet-fix-tso-v1-0-10cd07b54d1c@linaro.org
