[PATCH 2/3] IB core counters: Specify attribute_id in port_table_attribute

[Christoph Lameter <cl-vYTEC60ixJUAvxtiuMwx3w@public.gmane.org>]

[-- Attachment #1: ib_64bit_specify_attribute_id --]
[-- Type: text/plain, Size: 1714 bytes --]

Add the attr_id on port_table_attribute since we will have to add
a different port_table_attribute for the extended attribute soon.
