From 2d86051893fc2e813f26c16d13786bb377c26d48 Mon Sep 17 00:00:00 2001 From: cdoern Date: Sun, 5 Sep 2021 23:22:17 -0400 Subject: Pod Device-Read-BPS support added the option for the user to specify a rate, in bytes, at which they would like to be able to read from the device being added to the pod. This is the first in a line of pod device options.
