We are planning to move mfi and mrsas as loadable kernel module, once mrsas= driver is submitted. With this, we will provide device.hint tunable option= for customer to load mfi vs mrsas for Thunderbolt card. Best solution is not to have two drivers works with same hardware, but due = to development cycle LSI added immediate support for Thunderbolt card in current mfi driver. Now we have new driver developed fo= r the same card "mrsas". Customer also wanted to provide choice between mfi vs mrsas for Thunderbolt= card until they found "mrsas" is working fine without any major issue for = them. LSI decided based on customer request and they did not wanted to force cust= omers to use "mrsas" driver as immediate effect. There may be some customer= who are using "mfi" driver in production environment and do not want to sw= itch to "mrsas" if they upgrade FeeBSD kernel. This provision of mfi vs mrsas priority is only temporary and in future, we= should plan to remove Thunderbolt (Device ID 0x005B) from mfi because LSI = will continue new development on "mrsas" >=20 >=20 > _______________________________________________ > freebsd-scsi@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-scsi > To unsubscribe, send any mail to "freebsd-scsi-unsubscribe@freebsd.org"
