The MegaRAID SAS 8888ELP is still not recognized.

dmesg :

pci3: <PCI bus> on pcib3
pci3: <mass storage, RAID> (vendor 0x1000, dev 0x0060) at device 0.0 irq 11

pciconf -lv :

none17@pci0:3:0:0:      class=0x010400 card=0x10061000 chip=0x00601000 rev=0x04 hdr=0x00
    vendor     = 'LSI Logic (Was: Symbios Logic, NCR)'
    device     = 'SAS1078 PCI-X Fusion-MPT SAS'
    class      = mass storage
    subclass   = RAID

So it seems DragonFly doesn't support any recent hardware RAID controller.
