[legacy] Rename the global legacy NIC to "legacy_nic"

Browse Source 
We currently have contexts in which the local variable "nic" is a
pointer to the global variable also called "nic".  This complicates
the creation of macros.

Rename the global variable to "legacy_nic" to reduce pollution of the
global namespace and to allow for the creation of macros referring to
fields within this global variable.
