> There is one advantage of Linux over FreeBSD, which is not widely known. Linux has a huge database of known bugs in various peripheral devices, including Ethernet NICs, and when one of those is recognized it applies workarounds for the bugs.

Almost universal hardware support and workarounds for quirks is precisely the reason why everyone uses Linux even if they might want to use FreeBSD or something else. In other words, this advantage is known and is the reason why Linux is dominant in the server space today.
