From: Petr Oros Date: Thu, 12 Feb 2026 07:53:11 +0000 (+0100) Subject: ice: use ice_update_eth_stats() for representor stats X-Git-Tag: ceph-for-7.1-rc1~126^2~1^2~3 X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=2526e440df2725e7328d59b835a164826f179b93;p=ceph-client.git ice: use ice_update_eth_stats() for representor stats ice_repr_get_stats64() and __ice_get_ethtool_stats() call ice_update_vsi_stats() on the VF's src_vsi. This always returns early because ICE_VSI_DOWN is permanently set for VF VSIs - ice_up() is never called on them since queues are managed by iavf through virtchnl. In __ice_get_ethtool_stats() the original code called ice_update_vsi_stats() for all VSIs including representors, iterated over ice_gstrings_vsi_stats[] to populate the data, and then bailed out with an early return before the per-queue ring stats section. That early return was necessary because representor VSIs have no rings on the PF side - the rings belong to the VF driver (iavf), so accessing per-queue stats would be invalid. Move the representor handling to the top of __ice_get_ethtool_stats() and call ice_update_eth_stats() directly to read the hardware GLV_* counters. This matches ice_get_vf_stats() which already uses ice_update_eth_stats() for the same VF VSI in legacy mode. Apply the same fix to ice_repr_get_stats64(). Note that ice_gstrings_vsi_stats[] contains five software ring counters (rx_buf_failed, rx_page_failed, tx_linearize, tx_busy, tx_restart) that are always zero for representors since the PF never processes packets on VF rings. This is pre-existing behavior unchanged by this patch.
