svn commit: r320897 - in stable/11/sys: conf dev/ixgbe modules/ix modules/ixv

[Mike Tancsa]

Hi Eric,
	For stable users, can the loader.conf variable not be the original one
? Especially for servers that are physically remote, a sysadmin might
expect (wrongly or not) for the name not the change in a stable branch.
If the box is remote, they would not be able to see the new dmesg error.
Rather than change the name, perhaps a deprecation warning saying "In
FreeBSD 12, this will be hw.ix.allow_unsupported_sfp" ?

	---Mike
