Module Name:    src

Modified Files:
        src/sys/dev/pci: ubsec.c ubsecvar.h

Log Message:
Rewrite the dmamap handling to allocate and cache the dmamaps beforehand.
Calling bus_dmamap_create/destroy is no longer possible in interrupt context.
Move the dmamaps to the end of struct ubsec_q so the rest of the struct
can be cleared with one call to memset().

As a bonus we get a 25% increase in throughput encrypting 8K blocks.
