Identifying the Adapter
21
=======================
23
To find if one or more Pensando PCI Ethernet devices are installed on the
24
host, check for the PCI devices::
26
$ lspci -d 1dd8:
27
b5:00.0 Ethernet controller: Device 1dd8:1002
28
b6:00.0 Ethernet controller: Device 1dd8:1002
30
If such devices are listed as above, then the ionic.ko driver should find
31
and configure them for use. There should be log entries in the kernel
32
messages such as these::
34
$ dmesg | grep ionic
35
ionic 0000:b5:00.0: 126.016 Gb/s available PCIe bandwidth (8.0 GT/s PCIe x16 link)
36
ionic 0000:b5:00.0 enp181s0: renamed from eth0
37
ionic 0000:b5:00.0 enp181s0: Link up - 100 Gbps
38
ionic 0000:b6:00.0: 126.016 Gb/s available PCIe bandwidth (8.0 GT/s PCIe x16 link)
39
ionic 0000:b6:00.0 enp182s0: renamed from eth0
40
ionic 0000:b6:00.0 enp182s0: Link up - 100 Gbps
42
Driver and firmware version information can be gathered with either of
43
ethtool or devlink tools::
45
$ ethtool -i enp181s0
46
driver: ionic
47
version: 5.7.0
48

62
See Documentation/networking/devlink/ionic.rst for more information
63
on the devlink dev info data.
65
Enabling the driver
66
===================
68
The driver is enabled via the standard kernel configuration system,
69
using the make command::
71
make oldconfig/menuconfig/etc.
73
The driver is located in the menu structure at:
75
-> Device Drivers
76
-> Network device support (NETDEVICES [=y])
77
-> Ethernet driver support
78
-> Pensando devices
79
-> Pensando Ethernet IONIC Support
81
Configuring the Driver
82
======================
84
MTU
85
---
87
Jumbo frame support is available with a maximum size of 9194 bytes.
89
Interrupt coalescing
90
--------------------
92
Interrupt coalescing can be configured by changing the rx-usecs value with
93
the "ethtool -C" command. The rx-usecs range is 0-190. The tx-usecs value
94
reflects the rx-usecs value as they are tied together on the same interrupt.
96
SR-IOV
97
------
99
Minimal SR-IOV support is currently offered and can be enabled by setting
100
the sysfs 'sriov_numvfs' value, if supported by your particular firmware
101
configuration.
103
XDP
104
---
106
Support for XDP includes the basics, plus Jumbo frames, Redirect and
107
ndo_xmit. There is no current support for zero-copy sockets or HW offload.
109
RDMA Support via Auxiliary Device
110
=================================
112
The ionic driver supports RDMA (Remote Direct Memory Access) functionality
113
through the Linux auxiliary device framework when advertised by the firmware.
114
RDMA capability is detected during device initialization, and if supported,
115
the ethernet driver will create an auxiliary device that allows the RDMA
116
driver to bind and provide InfiniBand/RoCE functionality.
118
Statistics
119
==========
121
Basic hardware stats
122
--------------------
124
The commands ``netstat -i``, ``ip -s link show``, and ``ifconfig`` show
125
a limited set of statistics taken directly from firmware. For example::
127
$ ip -s link show enp181s0
128
7: enp181s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000
129

130
RX: bytes packets errors dropped overrun mcast
131
414 5 0 0 0 0
132
TX: bytes packets errors dropped carrier collsns
133
1384 18 0 0 0 0
135
ethtool -S
136
----------
138
The statistics shown from the ``ethtool -S`` command includes a combination of
139
driver counters and firmware counters, including port and queue specific values.
140
The driver values are counters computed by the driver, and the firmware values
141
are gathered by the firmware from the port hardware and passed through the
142
driver with no further interpretation.

드라이버 활성화, 네트워크 기능과 RDMA
65-117드라이버 활성화
드라이버는 표준 커널 구성 시스템에서 `make` 명령으로 활성화합니다.
make oldconfig/menuconfig/etc.메뉴에서 드라이버는 다음 위치에 있습니다.
Device Drivers
Network device support (NETDEVICES [=y])
Ethernet driver support
Pensando devices
Pensando Ethernet IONIC Support드라이버 구성
MTU
점보 프레임은 최대 9194바이트까지 지원됩니다.
인터럽트 병합
`ethtool -C` 명령의 `rx-usecs` 값을 변경해 인터럽트 병합을 구성할 수 있습니다. 범위는 0~190입니다. 송수신이 같은 인터럽트에 묶여 있으므로 `tx-usecs` 값은 `rx-usecs` 값을 그대로 반영합니다.
SR-IOV
현재는 최소한의 SR-IOV 기능을 제공합니다. 사용 중인 펌웨어 구성이 지원한다면 sysfs의 `sriov_numvfs` 값을 설정해 활성화할 수 있습니다.
XDP
기본 XDP 기능과 함께 점보 프레임, Redirect, `ndo_xmit`을 지원합니다. 제로 카피 소켓과 하드웨어 오프로딩은 현재 지원하지 않습니다.
보조 장치를 통한 RDMA 지원
펌웨어가 기능을 알리면 `ionic` 드라이버는 Linux auxiliary device 프레임워크를 통해 RDMA(Remote Direct Memory Access)를 지원합니다. 장치 초기화 과정에서 RDMA 기능을 감지하고, 지원되는 경우 Ethernet 드라이버가 보조 장치를 만듭니다. 그러면 RDMA 드라이버가 이 장치에 bind하여 InfiniBand/RoCE 기능을 제공합니다.
장치 초기화→펌웨어 RDMA 기능 감지→`ionic` auxiliary device 생성→RDMA 드라이버 bind→InfiniBand/RoCE 제공

Statistics
==========
Basic hardware stats
--------------------
The commands ``netstat -i``, ``ip -s link show``, and ``ifconfig`` show
a limited set of statistics taken directly from firmware. For example::
$ ip -s link show enp181s0
7: enp181s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000
link/ether 00:ae:cd:00:07:68 brd ff:ff:ff:ff:ff:ff
RX: bytes packets errors dropped overrun mcast
414 5 0 0 0 0
TX: bytes packets errors dropped carrier collsns
1384 18 0 0 0 0
ethtool -S
----------
The statistics shown from the ``ethtool -S`` command includes a combination of
driver counters and firmware counters, including port and queue specific values.
The driver values are counters computed by the driver, and the firmware values
are gathered by the firmware from the port hardware and passed through the
driver with no further interpretation.

요약·해설
ionic.rst:1-306`ionic`은 Pensando PCI Ethernet 장치를 구동하며 일반 네트워크 기능과 RDMA 보조 장치의 기반을 함께 제공합니다. 운영할 때는 `ethtool -i`와 `devlink dev info`로 버전을 확인하고, `ethtool -S`의 드라이버 계산값과 펌웨어 전달값을 구분해 읽는 것이 핵심입니다.
구성 항목별 인터페이스와 제한입니다.
장치 인식부터 통계 진단까지의 기본 흐름입니다.
