+Neterion's (Formerly S2io) X3100 Series 10GbE PCIe Server Adapter Linux driver
+==============================================================================

+4) Troubleshooting
+
+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
+ Enable learning the mac address of the guest OS interface in
+ virtualization environment.
+ Valid range: 0,1 (disabled, enabled respectively)
+ Default: 0
