The original code would incorrectly hardcode ELS timeout values
rather than using the traditional '2 * r_a_tov' value. In some
cases, the hardcoded values would be larger than the
mailbox-command-timeout and result in a needless BIG_HAMMER (ISP
reset), the typical recovery mechanism employed in such cases.
The second defect in the original code was in the assignment of
the default 'ha->r_a_tov' to twice the traditional value.
Correct this by setting the value to 10 seconds.

For recent ISPs, software must detect OVERRUN conditions by
checking the SS_RESIDUAL_OVER bit during CS_COMPLETE handling.
Update the driver to perform this check, which is consistent with
what earlier firmwares did by explicitly cracking open the
FCP_RSP statuses and returning an CS_DATA_OVERRUN.

There's no point in hitting the RISC with what will most
assuredly be an unsucessful reset of the RISC hardware if the
initial stop-firmware mailbox command fails with a time-out
status. Instead, to avoid what could amount to a lengthy
stop-firmware/detect-failure/reset-risc loop, continue with
driver unloading and discard the stop-firmware requirement.

So, this patch changed way to access the data for those attributes so that
they can access pport's.
- get_host_speed (speed)
- get_host_port_state (port_state)
- get_host_port_type (port_type)

Also, added PORT_SPEED_8GB case in the speed attribute for 8Gb HBAs.

FCE support enables the firmware to record FC extended link
services and basic link services frames which have been
transmitted and received by the ISP. This allows for a limited
view of the FC traffic through the ISP without using a FC
analyzer. This can be useful in situations where a physical
connection to the FC bus is not possible.
The driver exports this information in two ways -- first, via a
debugfs node exported for all supported ISPs under:
<debugfs_mount_point>/qla2xxx/qla2xxx_<host_no>/fce
where a read of the 'fce' file will provide a snapshot of the
firmware's FCE buffer; and finally, the FCE buffer will be
extracted during a firmware-dump scenario.

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.
