[PATCH net-next 4/7] net: ipa: open-code ether_setup()

From: Alex Elder
Date: Thu May 19 2022 - 11:12:58 EST


About half of the fields set by the call in ipa_modem_netdev_setup()
are overwritten after the call. Instead, just skip the call, and
open-code the (other) assignments it makes to the net_device
structure fields.
