[PATCH 0/5][SRU][F] Add r8117 support and fix firmware base issue

[Aaron Ma]

BugLink: https://bugs.launchpad.net/bugs/1885072

[Impact]
Realtek 8117 is failed to be initialized on 5.4- kernel,
even failed to work after loading firmware on 5.5+ kernel.

[Fix]
Add rtl8117 support for 5.4- kernel.
On 5.5+ kernel, firmware should reset ocp_base, but not on r8117.
Correct the ocp_base in the driver.
Then it works well.

[Test]
Verified on hardware, link status is OK, iperf test result is good.

[Regression Potential]
Low.
Fixed issue, cherry-picked from linux-next tree.
SRU for OEM-5.6/U was already done. this is for focal because of more
commits.
Bionic kernel set rtl8117 as default r8169. It just works. no need these
changes.

Backport 0002 patch because of another upstream patch is already merged.

Heiner Kallweit (5):
  r8169: add helper r8168g_phy_param
  r8169: add support for RTL8117
  r8169: load firmware for RTL8168fp/RTL8117
  r8169: fix OCP access on RTL8117
  r8169: fix firmware not resetting tp->ocp_base
