Implement TPH support in Broadcom BNXT device driver by invoking
pcie_tph_set_st() function when interrupt affinity is changed.

*and* invoking pcie_tph_set_st() when setting up the IRQ in the first
place, I guess?

I guess this gives a significant performance benefit?  The series
includes "pci=nostmode" so the benefit can be quantified, so now I'm
curious about what you measured :)

Using network benchmarks, three main metrics were measured: network latency, network bandwidth, and memory bandwidth saving.


+static void bnxt_rtnl_lock_sp(struct bnxt *bp);
+static void bnxt_rtnl_unlock_sp(struct bnxt *bp);

These duplicate declarations can't be right, can they?  OK for
work-in-progress, but it doesn't look like the final solution.

Will fix.
