Hi Jobst, Brent, and Hakan,
Thanks for your inputs. I sincerely appreciate your suggestions and sharing your experience.
I have posted a support query with Chelsio as well.
In my case the connection is a Fiber cable. On the switch side there is only one 10GB port so there is not much I can do. Luckily the switch and the cable, besides the NIC, has also been supplied by the same vendor.
I am going to request the hardware vendor to send their engineer and to take on the next steps.
Will post final findings over here when the problem is solved.
