Hi James,

the aic7xxx drivers do not set .max_sectors, and hence defaults to 512kB. The adaptec sources indicate that it in realiter can handle up to 4MB, so there is no reason not to adjust it.

Please apply,

Hannes

aic7xxx: Adjust .max_sectors

According to the adaptec sources aic7xxx / aic79xx really can do 4MB transfers. So we should adjust .max_sectors.
