I am wondering what kind of support I can get from linux for
"inexpensive" (SATA over SAS HBA in my case) disks on RAID ...
Inexpensive non-raid-edition disks haven't got settable ERC timeout
(scterc) and can take very long time to respond in case of unreadable sector
However I see

we use strncpy to copy a model name of length up to 15 (16, if you count
the NUL), into a buffer of size 12 (BFA_FCS_PORT_SYMBNAME_MODEL_SZ).
However, strncpy does not always NUL-terminate, so whenever the original
model string has strlen >= 12, the following strncat reads beyo

be2iscsi: Removing the iscsi_data_pdu setting.

The setting of iscsi_data_pdu is not required anymore,
as this was required for BE1 adapters only. The BE1 adapter
were not supported in any previous versions of the kernel.

sorry for the long delay until I finally responded.
Thanks a lot for your report and patch.
I'll queue this and send it for v3.6rcX hopefully soon.
