I don't see those options listed:

you're not looking in the right place, look in TFM: /usr/share/doc/initscripts-*/sysconfig.txt _______________________________________________
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.
