This is a note to let you know that I've just added the patch titled RDMA/irdma: Report the correct link speed to the 5.15-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: rdma-irdma-report-the-correct-link-speed.patch and it can be found in the queue-5.15 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 0e35824ee1df9806f1d816f3a29ebbba288c59e3 Author: Shiraz Saleem <shiraz.saleem@xxxxxxxxx> Date: Fri Nov 4 18:49:57 2022 -0500 RDMA/irdma: Report the correct link speed [ Upstream commit 4eace75e0853273755b878ffa9cce6de84df975a ] The active link speed is currently hard-coded in irdma_query_port due to which the port rate in ibstatus does reflect the active link speed. Call ib_get_eth_speed in irdma_query_port to get the active link speed.
