Interesting. It *almost* looks like a plain text (i.e. instructions /
manual) file to me and there's 2 lines with the option you specified:
ETHTOOL_OPTS=...
Any device-specific options supported by ethtool. For example,
if you wanted to force 100Mb full duplex:
ETHTOOL_OPTS="speed 100 duplex full autoneg off"
The NIC is connected @ 1GB, as per the switch interface, but I can't
seem to verify it on CentOS directly, and I would prefer not to change
this file since it shows as 100MB (if that 2nd line with ETHTOOL_OPTS
is an actual configuration option, and not just comment) but there's
no mention of Flow Control in that file. I don't know what impact this
could have, if any at all.
