Subject: [PATCH] r8169: never set PCI_EXP_DEVCTL_NOSNOOP_EN
Git-commit: 06cd9da58fb25526bd1a4b0f36e25e1a8824ea1f
Patch-mainline: v5.5-rc1
References: bsc#1175746
Setting PCI_EXP_DEVCTL_NOSNOOP_EN for certain chip versions had been
added to the vendor driver more than 10 years ago, and copied from
there to r8169. It has been removed from the vendor driver meanwhile
and I think we can safely remove this too.
