It is pointless to attempt an operation that is not permitted. It spams the firmware devlog with "insufficient caps" errors that distract from real errors. 78 2463625358 ERR CORE insufficient caps to process mailbox cmd: pfn 0x0 vfn 0x1; r_caps 0x86 wx_caps 0x82 required r_caps 0x81 w_caps 0x5 MFC after: 1 week Sponsored by: Chelsio Communications --- sys/dev/cxgbe/t4_main.c | 36 +++++++++++++++++++----------------- 1 file changed, 19 insertions(+), 17 deletions(-) diff --git a/sys/dev/cxgbe/t4_main.c b/sys/dev/cxgbe/t4_main.c index 03b674cb9241..ae18efb25f15 100644 --- a/sys/dev/cxgbe/t4_main.c +++ b/sys/dev/cxgbe/t4_main.c @@ -6023,25 +6023,27 @@ apply_link_config(struct port_info *pi) if (lc->requested_fec & FEC_BASER_RS) MPASS(lc->pcaps & FW_PORT_CAP32_FEC_BASER_RS); #endif - rc = -t4_link_l1cfg(sc, sc->mbox, pi->tx_chan, lc); - if (rc != 0) { - /* Don't complain if the VF driver gets back an EPERM. */ - if (!(sc->flags & IS_VF) || rc != FW_EPERM) + if (!(sc->flags & IS_VF)) { + rc = -t4_link_l1cfg(sc, sc->mbox, pi->tx_chan, lc); + if (rc != 0) { device_printf(pi->dev, "l1cfg failed: %d\n", rc); - } else { - /* - * An L1_CFG will almost always result in a link-change event if - * the link is up, and the driver will refresh the actual - * fec/fc/etc. when the notification is processed.
