Hi All,
This patch series adds support for Chelsio's T5 adapter. It also adds support
for new features of T5. It adds these in cxgb4, cxgb4vf, RDMA/cxgb4 and
csiostor drivers.
Chelsio's T5 asic moves the architecture into 40GbE speeds. T5 is a 10/40GbE
controller with full offload support of a co

It enables direct DMA by HW to memory region PBL arrays and fast register PBL
arrays from host memory, vs the T4 way of passing these arrays in the WR itself.
The result is lower latency for memory registration, and larger PBL array
support for fast register operations.
This patch also updates ULP

Just for my understanding:
So this is a bit like writing 0 into the failed attribute of a zfcp_port
in sysfs (zfcp_sysfs_port_failed_store()) which forces a port reopen
recovery including a sequence of fc_remote_port_delete and
fc_remote_port_add?
If so, it sounds good to have this functionalit
