|
||||
1) Introduction:
|
||||
----------------
|
||||
This Linux driver supports all Neterion's X3100 series 10 GbE PCIe I/O
|
||||
Virtualized Server adapters.
|
||||
The X3100 series supports four modes of operation, configurable via
|
||||
firmware -
|
||||
Single function mode
|
||||
Multi function mode
|
||||
SRIOV mode
|
||||
MRIOV mode
|
||||
The functions share a 10GbE link and the pci-e bus, but hardly anything else
|
||||
inside the ASIC. Features like independent hw reset, statistics, bandwidth/
|
||||
priority allocation and guarantees, GRO, TSO, interrupt moderation etc are
|
||||
supported independently on each function.
|
||||
|
||||
(See below for a complete list of features supported for both IPv4 and IPv6)
|
||||
|
||||
2) Features supported:
|
||||
----------------------
|
||||
|
||||
i) Single function mode (up to 17 queues)
|
||||
|
||||
ii) Multi function mode (up to 17 functions)
|
||||
|
||||
iii) PCI-SIG's I/O Virtualization
|
||||
- Single Root mode: v1.0 (up to 17 functions)
|
||||
- Multi-Root mode: v1.0 (up to 17 functions)
|
||||
|
||||
iv) Jumbo frames
|
||||
X3100 Series supports MTU up to 9600 bytes, modifiable using
|
||||
ifconfig command.
|
||||
|
||||
v) Offloads supported: (Enabled by default)
|
||||
Checksum offload (TCP/UDP/IP) on transmit and receive paths
|
||||
TCP Segmentation Offload (TSO) on transmit path
|
||||
Generic Receive Offload (GRO) on receive path
|
||||
|
||||
vi) MSI-X: (Enabled by default)
|
||||
Resulting in noticeable performance improvement (up to 7% on certain
|
||||
platforms).
|
||||
|
||||
vii) NAPI: (Enabled by default)
|
||||
For better Rx interrupt moderation.
|
||||
|
||||
viii)RTH (Receive Traffic Hash): (Enabled by default)
|
||||
Receive side steering for better scaling.
|
||||
|
||||
ix) Statistics
|
||||
Comprehensive MAC-level and software statistics displayed using
|
||||
"ethtool -S" option.
|
||||
|
||||
x) Multiple hardware queues: (Enabled by default)
|
||||
Up to 17 hardware based transmit and receive data channels, with
|
||||
multiple steering options (transmit multiqueue enabled by default).
|
||||
|
||||
3) Configurable driver parameters:
|
||||
----------------------------------
|
||||
|
||||
i) max_config_dev
|
||||
Specifies maximum device functions to be enabled.
|
||||
Valid range: 1-8
|
||||
|
||||
ii) max_config_port
|
||||
Specifies number of ports to be enabled.
|
||||
Valid range: 1,2
|
||||
Default: 1
|
||||
|
||||
iii)max_config_vpath
|
||||
Specifies maximum VPATH(s) configured for each device function.
|
||||
Valid range: 1-17
|
||||
|
||||
iv) vlan_tag_strip
|
||||
Enables/disables vlan tag stripping from all received tagged frames that
|
||||
are not replicated at the internal L2 switch.
|
||||
Valid range: 0,1 (disabled, enabled respectively)
|
||||
Default: 1
|
||||
|
||||
v) addr_learn_en
|
||||

|
||||

|
||||
Valid range: 0,1 (disabled, enabled respectively)
|
||||
