<div class="bz_comment_block">
<pre class="bz_comment_text">On Intel® Ethernet Controller 82599EB When Ethertype filter (priority enable)
was set, unmatched packets also could be received on the assigned queue, such
as ARP packets without 802.1q tags or with the user priority not equal to set
value. Launch the testpmd by disabling RSS and with multiply queues, then add
the ethertype filter like the following and then start forwarding:
add_ethertype_filter 0 ethertype 0x0806 priority enable 3 queue 2 index 1
When sending ARP packets without 802.1q tag and with user priority as non-3 by
tester, all the ARP packets can be received on the assigned queue.
Implication:
The user priority comparing in Ethertype filter cannot work probably. It is a
NIC’s issue due to the following: “In fact, ETQF.UP is not functional, and the
information will be added in errata of 82599 and X540.”
Resolution/Workaround:
None
Affected Environment/Platform:
All.
Driver/Module:
Poll Mode Driver (PMD).
