Add the new opcodes and struct used for asking the firmware to update Rx
control registers that need extra care when being accessed while under
heavy traffic - e.g. sustained 64byte packets at line rate on all ports.
The firmware will take extra steps to be sure the register accesses
are successful.

The registers involved are:
	PFQF_CTL_0
	PFQF_HENA
	PFQF_FDALLOC
	PFQF_HREGION
	PFLAN_QALLOC
	VPQF_CTL
	VFQF_HENA
	VFQF_HREGION
	VSIQF_CTL
	VSILAN_QBASE
	VSILAN_QTABLE
	VSIQF_TCREGION
	PFQF_HKEY
	VFQF_HKEY
	PRTQF_CTL_0
	GLFCOE_RCTL
	GLFCOE_RSOF
	GLQF_CTL
	GLQF_SWAP
	GLQF_HASH_MSK
	GLQF_HASH_INSET
	GLQF_HSYM
	GLQF_FC_MSK
	GLQF_FC_INSET
	GLQF_FD_MSK
	PRTQF_FD_INSET
	PRTQF_FD_FLXINSET
	PRTQF_FD_MSK
