2012-05-14	IB/qib: Display correct value for number of contexts	Mitko Haralanov	1	-2/+5
	A "fix" for a bug with the number of contexts on a single-port board caused the calculation to be off by one, which causes problems with the upper layers. The same problem exists for number of free contexts, which is also fixed here.

2011-10-06	IB/qib: Correct nfreectxts for multiple HCAs	Mike Marciniszyn	1	-2/+1
	The code that was recently introduced to report the number of free contexts is flawed for multiple HCAs: /* Return the number of free user ports (contexts) available. */ return scnprintf(buf, PAGE_SIZE, "%u\n", dd->cfgctxts - dd->first_user_ctxt - (u32)qib_stats.sps_ctxts); The qib_stats is global to the module, not per HCA, so the code is broken for multiple HCAs. This patch adds a qib_devdata field, freectxts, that reflects the free contexts for this HCA.
