net: Remove unneeded NULL check for the allocated ifnet

2024-07-12T12:03:37+00:00

Change 4787572d0580 made if_alloc_domain() never fail, then also do the
wrappers if_alloc(), if_alloc_dev(), and if_gethandle().

No functional change intended.

ar40xx_switch: add initial switch for the IPQ4018/IPQ4019.

2022-02-04T05:27:13+00:00

Summary:

This switch is based off of the AR8327/AR8337 external switch/PHY.
However unlike the AR8327/AR8337 it itself doesn't have any PHYs;
instead an external PHY connects to it using the PSGMII port.

This code is inspired by the ar40xx code in openwrt, which itself
is based on the Qualcomm QCA-SSDK.  Both of these sources are, amusingly,
BSD licenced - and thus I have included some of the comments in the
hardware workaround paths to document some of the magic numbers.
