[p]On Parabola it doesn't work out of the box because for some reason the libre kernel blacklists the free tg3 driver (which is required). Broadcom Tigon3 deblob from [a]https://linux-libre.fsfla.org/pub/linux-libre/releases/LATEST-5.3.N/deblob-5.3[/a] removes both the proprietary firmware and the driver from the kernel itself even though for this model, the firmware is not necessary for it to work acording to [a]https://unix.stackexchange.com/questions/336917/tigon-ethernet-firmware-error-message-though-working[/a] which says that firmware is only needed for BCM5705 TSO, BCM5703/BCM5704 TSO and BCM5701A0 (Maybe they thought that all models need firmware to work). This is BCM5782 which continues to work even after deleting the entire /lib/firmware/tigon/ directory from a non-free distro. The stack exchange post also mentions a problem with the light indicator, which i did not encounter.[/p]

Lack of the driver means the presence of the card doesn't appear in dmesg but lspci
works.

For some reason unlike other cards it fails to configure the interface during the boot so the command must be used afterwards. This is the log produced in dmesg by [code]dhclient[/code]

The lease is longer than usual (5-7 seconds) but after that it works perfectly and no proprietary software is used!
