net/ncsi: Simplify Kconfig/dts control flow
[ Upstream commit c797ce1 ] Background: 1. CONFIG_NCSI_OEM_CMD_KEEP_PHY If this is enabled, we send an extra OEM Intel command in the probe sequence immediately after discovering a channel (e.g. after "Clear Initial State"). 2. CONFIG_NCSI_OEM_CMD_GET_MAC If this is enabled, we send one of 3 OEM "Get MAC Address" commands from Broadcom, Mellanox (Nvidida), and Intel in the *configuration* sequence for a channel. 3. mellanox,multi-host (or mlx,multi-host) Introduced by this patch: https://lore.kernel.org/all/20200108234341.2590674-1-vijaykhemka@fb.com/ Which was actually originally from cosmo.chou@quantatw.com: facebook/openbmc-linux@9f132a1 Cosmo claimed that the Nvidia ConnectX-4 and ConnectX-6 NIC's don't respond to Get Version ID, et. al in the probe sequence unless you send the Set MC Affinity command first. Problem Statement: We've been using a combination of #ifdef code blocks and IS_ENABLED() conditions to conditionally send these OEM commands. It makes adding any new code around these commands hard to understand. Solution: In this patch, I just want to remove the conditionally compiled blocks of code, and always use IS_ENABLED(...) to do dynamic control flow. I don't think the small amount of code this adds to non-users of the OEM Kconfigs is a big deal. Signed-off-by: Peter Delevoryas <peter@pjd.dev> Signed-off-by: David S.
