Also: - add missing opt_rss.h to if_ixv.c, otherwise RSS kernel option could not be seen - do not enable IXGBE_FEATURE_RSS on the older VFs - set flowid / hash type to M_HASHTYPE_NONE or M_HASHTYPE_OPAQUE_HASH (based on what the hardware reports) if IXGBE_FEATURE_RSS is not set Reviewed by: nobody MFC after: 4 weeks Sponsored by: Panzura Differential Revision: https://reviews.freebsd.org/D21705 Modified: head/sys/dev/ixgbe/if_ixv.c head/sys/dev/ixgbe/ix_txrx.c Modified: head/sys/dev/ixgbe/if_ixv.c ============================================================================== --- head/sys/dev/ixgbe/if_ixv.c Tue Nov 5 03:22:15 2019 (r354348) +++ head/sys/dev/ixgbe/if_ixv.c Tue Nov 5 06:34:20 2019 (r354349) @@ -35,6 +35,7 @@ #include "opt_inet.h" #include "opt_inet6.h" +#include "opt_rss.h" #include "ixgbe.h" #include "ifdi_if.h" @@ -1454,7 +1455,12 @@ ixv_initialize_receive_units(if_ctx_t ctx) scctx->isc_nrxd[0] - 1); } - ixv_initialize_rss_mapping(adapter); + /* + * Do not touch RSS and RETA settings for older hardware + * as those are shared among PF and all VF. + */ + if (adapter->hw.mac.type >= ixgbe_mac_X550_vf) + ixv_initialize_rss_mapping(adapter); } /* ixv_initialize_receive_units */ /************************************************************************ @@ -1889,7 +1895,6 @@ ixv_init_device_features(struct adapter *adapter) { adapter->feat_cap = IXGBE_FEATURE_NETMAP | IXGBE_FEATURE_VF - | IXGBE_FEATURE_RSS | IXGBE_FEATURE_LEGACY_TX; /* A tad short on feature flags for VFs, atm. */ @@ -1902,6 +1907,7 @@ ixv_init_device_features(struct adapter *adapter) case ixgbe_mac_X550EM_x_vf: case ixgbe_mac_X550EM_a_vf: adapter->feat_cap |= IXGBE_FEATURE_NEEDS_CTXD; + adapter->feat_cap |= IXGBE_FEATURE_RSS; break; default: break; Modified: head/sys/dev/ixgbe/ix_txrx.c ============================================================================== --- head/sys/dev/ixgbe/ix_txrx.c Tue Nov 5 03:22:15 2019 (r354348) +++ head/sys/dev/ixgbe/ix_txrx.c Tue Nov 5 06:34:20 2019 (r354349) @@ -464,6 +464,12 @@ ixgbe_isc_rxd_pkt_get(void *arg, if_rxd_info_t ri) ri->iri_flowid = le32toh(rxd->wb.lower.hi_dword.rss); ri->iri_rsstype = ixgbe_determine_rsstype(pkt_info); + if ((adapter->feat_en & IXGBE_FEATURE_RSS) == 0) { + if (ri->iri_rsstype == M_HASHTYPE_OPAQUE) + ri->iri_rsstype = M_HASHTYPE_NONE; + else + ri->iri_rsstype = M_HASHTYPE_OPAQUE_HASH; + } ri->iri_vtag = vtag; ri->iri_nfrags = i; if (vtag)
