If EEDPTagMode field in manufacturing page11 is set then
unset it. This is needed to fix a hardware bug only
in SAS3/SAS2 cards. So, skipping EEDPTagMode changes
in Manufacturing page11 for SAS 3.5 controllers.

Once sas_remove_host() is called before removing the target drives then
driver can just clean up the resources allocated for target devices and
no need to call sas_port_delete_phy(), sas_port_delete() API's as these
API's internally called from sas_remove_host().

s which are issued to the
target drives (where write cache is enabled) during driver unload time
is failed with DID_NO_CONNECT status.
Now modified the driver to allow SYNC CACHE and START STOP commands
to IOC, even when remove_host flag is set.

No functional changes. This section of code "wait for IOC to be
operational" is used in many places across the driver. Factor
this code out into a new mpt3sas_wait_for_ioc().

Any update on this ?
In V6, I have posted has only defect fixes (Other than HBA Hot-Plug

We are reworking and incorporating the suggestions from Bjorn.
And after covering tests, we ll post Hot-Plug Surprise removal patches.
Thanks,
