From: Quinn Tran <qutran@xxxxxxxxxxx> commit beafd692461443e0fb1d61aa56886bf85ef6f5e4 upstream. For fabric scan, current code uses switch scan opcode and flags as the method to iterate through different commands to carry out the process. This makes it hard to read. This patch convert those opcode and flags into steps. In addition, this help reduce some duplicate code. Consolidate routines that handle GPNFT & GNNFT.
