I think the problem is that libibumad is masking the information. AFAICT the kernel reports "2.5" in sysfs. I'm concerned that there are probably lots of other places in the software stack which have this bug because libibumad is masking the rate. If the value of "2" was at least documented to be special and meant "2.5" I think this could be an ok patch... Something like else if (port->rate == UMAD_2_5_RATE) printf("%sRate: 2.5\n", pre); else printf("%sRate: %d\n", pre, port->rate); Ira > --- > diff --git a/src/ibstat.c b/src/ibstat.c > index 37f2361..2d980c4 100644 > --- a/src/ibstat.c > +++ b/src/ibstat.c > @@ -182,8 +182,10 @@ static int port_dump(umad_port_t * port, int alone) > 7 ? port_phy_state_str[port->phys_state] : "???"); > if (is_fdr10(port)) > printf("%sRate: %d (FDR10)\n", pre, port->rate); > - else > + else if (port->rate != 2) /* 1x SDR */ > printf("%sRate: %d\n", pre, port->rate); > + else > + printf("%sRate: 2.5\n", pre); > printf("%sBase lid: %d\n", pre, port->base_lid); > printf("%sLMC: %d\n", pre, port->lmc); > printf("%sSM lid: %d\n", pre, port->sm_lid); -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
