[PATCH v6 28/30] PCI/portdrv: Declare support of movable BARs

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Switch's BARs are not used by the portdrv driver, but they are still
considered as immovable until the .rescan_prepare() and .rescan_done()
hooks are added. Add these hooks to increase chances to allocate new BARs.
