While upgrading a Brocade ICX7250 firmware from version 8.0.30 to 8.0.40, I noticed issues on the ssh (scp) client of the switch while transferring firmware from a Linux SSH server.
I executed this command on the Brocade switch with management IP (10.1.1.101) to copy the firmware (spz10106.bin) from the SSH server (10.1.1.111)

Below is the error logs from the Linux server (10.1.1.111).
