[c-nsp] 3750 and CVE-2018-0167

[Chuck Church]

I thought with LLDP you can turn off receive and transmit of LLDP messages
separately.  If you disable the receipt of them and only transmit, does
that address the issue?  These switches are end of all support dates.  They
most surely won't address this bug.
