That=E2=80=99= s at least one rtattr that=E2=80=99s null in print_qdisc on MIPS for = some reason. That=E2=80=99s where I=E2=80=99m at, anyway=E2=80=A6 I should have written that the rtattr at TCP_STATS2 has a zero len and = type in it, not that it=E2=80=99s null. But, um, I find it curious that tb[TCA_PAD] has valid looking values in = it, and if I just go: tb[TCA_STATS2] =3D tb[TCA_PAD] right after parse_rtattr is called, I start getting tin stats printed = that look valid. There should be zeroes or invalid values at = tb[TCA_PAD], as that=E2=80=99s just supposed to be padding, right?
