Bug ID: 99
Summary: axgbe driver does not support 1G Copper 1000BASE-T
SFPs (Unsupported AN_CL37)
Product: DPDK
Version: 18.02
Hardware: All
OS: All
Status: CONFIRMED
Severity: normal
Priority: Normal
Component: ethdev
Assignee: dev@dpdk.org
Reporter: arsalan_a...@mentor.com
Target Milestone: ---
Overview:
The AXGBE driver does not support 1G Copper 1000BASE-T SFPs. When any of the
DPDK test apps (such as: l2fwd, kni etc) are run, the following errors show up:
axgbe_an_init(): Unsupported AN_CL37
axgbe_an_enable_interrupts(): Unsupported AN_MOD_37
axgbe_an_init(): Unsupported AN_CL37
axgbe_an_restart(): Unsupported AN_MODE_CL37
Looking into the AXGBE driver code, it seems like the "Clause 37
Auto-Negotiation (AN_CL37)" protocol being used by these SFPs is not
yet-supported/yet-implemented in the DPDK AXGBE Poll Mode Driver.
Steps to Reproduce:
1) Setup DPDK (hugepages, igb_uio, dpdk-devbind):
mkdir -p /mnt/huge
mount -t hugetlbfs nodev /mnt/huge
echo 1024 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages
modprobe igb_uio
dpdk-devbind -b igb_uio 03:00.4
dpdk-devbind -b igb_uio 03:00.5
2) Run any of the DPDK examples/tests (such as: l2fwd, kni etc) and observe the
output:
/usr/share/dpdk/examples/l2fwd/l2fwd -- -p 1 -T 1
Actual Results: (Using 1G Copper 1000BASE-T SFP)
