a version of the broadcom genet driver for rhel8 on rpi4 running uefi from rpi4-uefi.dev
This is mainly copied from Linus' tree (24085f70a6e1b0cb647ec92623284641d8270637 Tue May 12 11:06:26 2020 -0700) and then hacked to backport it to RHEL8. Its been tested on the 4.18.0-193.1.2.el8_2.aarch64 kernel and I expect it to work elsewhere but I haven't extensivly tested it as yet.
This is experimental, unsupported, may kill kittens, and will quite possibly panic your kernel if you hit an edge case.
To compile simply run
make
Then either install the module directly using insmod genet.ko or make install and reboot
