	---help---
	  SMC-R provides a "sockets over RDMA" solution making use of
	  RDMA over Converged Ethernet (RoCE) technology to upgrade
	  AF_INET TCP connections transparently.
	  The Linux implementation of the SMC-R solution is designed as
	  a separate socket family SMC.

	  Select this option if you want to run SMC socket applications

PCI/MSI: Don't apply affinity if there aren't enough vectors left
Bart reported a problem wіth an out of bounds access in the low-level IRQ affinity code, which we root caused to the qla2xxx driver assigning all its MSI-X vectors to the pre and post vectors, and not having any left for the actually spread IRQs. Fix this issue by not asking for affinity assignment when there are no vectors to assign left.
