The lantiq patch 0028-NET-lantiq-various-etop-fixes.patch and sunxi
patch 0051-stmmac-form-4-11.patch no longer applied after applying the
the "generalize napi_complete_done()" patch.
Update them so they apply, and refresh patches while at it.
Fixes: 9aeb7ce8dc ("generic: net: generalize napi_complete_done")

Subject: [PATCH] net: mvneta: disable MVNETA_CAUSE_PSC_SYNC_CHANGE
|
|
interrupt
|
|
|
|
The PSC sync change interrupt can fire multiple times while the link is
|
|
down. As this isn't information we make use of, it's pointless having
|
|
the interrupt enabled, so let's disable this interrupt.
