[ Upstream commit 7573099e10ca69c3be33995c1fcd0d241226816d ]
Static code analyzer complains to unchecked return value.
The result of pci_reset_function() is unchecked.
Despite, the issue is on the FLR supported code path and in that
case reset can be done with pcie_flr(), the patch uses less invasive
approach by adding the result check of pci_reset_function().

For l3s mode, skb->dev is set to ipvlan interface in ipvlan_nf_input():
skb->dev = addr->master->dev
but, skb->skb_iif remain unchanged, this will cause socket lookup failed
if a target socket is bound to a interface, like the following example:
ip link add ipvlan0 link eth0 type ipvlan mode l3s
ip addr add dev ipvlan0 192.168.124.111/24
ip link set ipvlan0 up
ping -c 1 -I ipvlan0 8.8.8.8
100% packet loss
This is because there is no match sk in __raw_v4_lookup() as sk->sk_bound_dev_if != dif(skb->skb_iif).
Fix this by make skb->skb_iif track skb->dev in ipvlan_nf_input().

Move the LAN7800 internal phy (phy ID 0x0007c132) specific register
accesses to the phy driver (microchip.c).
Fix the error reported by Enguerrand de Ribaucourt in December 2022,
"Some operations during the cable switch workaround modify the register
LAN88XX_INT_MASK of the PHY. However, this register is specific to the
LAN8835 PHY. For instance, if a DP8322I PHY is connected to the LAN7801,
that register (0x19), corresponds to the LED and MAC address
configuration, resulting in unapropriate behavior."
I did not test with the DP8322I PHY, but I tested with an EVB-LAN7800

commit 2a86aa9a1892d60ef2e3f310f5b42b8b05546d65 upstream.
The Realtek rate control algorithm goes back and forth a lot between
the highest and the lowest rate it's allowed to use. This is due to
a lot of frames being dropped because the retry limits set by
IEEE80211_CONF_CHANGE_RETRY_LIMITS are too low. (Experimentally, they
are 4 for long frames and 7 for short frames.)
The vendor drivers hardcode the value 48 for both retry limits (for
station mode), which makes dropped frames very rare and thus the rate
control is more stable.
Because most Realtek chips handle the rate control in the firmware,
which can't be modified, ignore the limits set by
IEEE80211_CONF_CHANGE_RETRY_LIMITS and use the value 48 (set during
chip initialisation), same as the vendor drivers.
