Drivers do SCRs for each Vport. When something changes in the
fabric, firmware generates one interrupt for each RSCN. Based on
the current implementation, in each case, we make recursive calls
to handle RSCN for physical and each subsequent virtual ports.
The fix is to also take into consideration the vp_idx, which is
set by the firmware to indicate the vport the RSCN was meant for.

Callers of qla2x00_async_event() already populate the mb[] array
upon invocation, doing so via the appropriate mailbox register
accessors. The stale codes removed are leftover-bits kept during
the FWI2 transition. Though relatively benign, the extra-reads
are not valid for FWI2 boards (ISP24xx and above) and peek into
the incorrect regions of registers.

For recent ISPs, software during CS_UNDERRUN handling must
determine if the two residuals, firmware-calculated and FCP_RSP,
are different to recognize if a frame has been dropped. Update
the driver to catch this condition, and clear the
SS_RESIDUAL_UNDER and lscsi_status bits. This logic is
consistent with what earlier firmwares did by explicitly
cracking open the FCP_RSP statuses and clearing
SS_RESIDUAL_UNDER.

Recent ISPs need only the single MMIO BAR to manipulate HW
registers. Unfortunately, ISP21xx, ISP22xx, ISP23xx, and ISP63xx
type cards still require the I/O mapped region to manipulate the
FLASH via the two HW flash-registers (flash_address and
flash_data).

Since both NVRAM and VPD regions of the flash reside on unaligned

Since MSI-X vectors do not require a clearing "handshake" from
the system perspective, and the registered handler will not be
called more than once for one occurrence of receipt of a vector,
there is no requirement to flush the risc register write clearing
the interrupt condition in the risc. Also, since the msi-x
registered handlers are optimised for a particular vector, it is
preferable to handle the one vector received per invocation of
the handler.
