From a8ff4842da50b5f4ea03d5d38a2ee93b701fe8e6 Mon Sep 17 00:00:00 2001 From: Breno Leitao Date: Fri, 21 Nov 2025 01:59:23 -0800 Subject: [PATCH] net: hyperv: convert to use .get_rx_ring_count Convert the hyperv netvsc driver to use the new .get_rx_ring_count ethtool operation instead of implementing .get_rxnfc solely for handling ETHTOOL_GRXRINGS command. This simplifies the code by replacing the switch statement with a direct return of the queue count. The new callback provides the same functionality in a more direct way, following the ongoing ethtool API modernization.
