30 #---------------Link Configuration ----------------------
31 # The link parameters depend on the type of the card
32 # and the port.
33 # 10 gigabit related parameters ( i.e adv_10gfdx_cap)
34 # apply only to 10gigabit ports.
35 # Half duplex is not supported on any NIU card.

72 #------- Receive DMA Configuration ----------------------------
73 #
74 # rxdma-intr-time
75 # Interrupts after this number of NIU hardware ticks have
76 # elapsed since the last packet was received.
77 # (Default = 8, Minimum = 1).
78 #
79 # rxdma-intr-pkts
80 # Interrupt after this number of packets have arrived since
81 # the last packet was serviced.
82 # (Default = 32, Minimum = 8).
83 #
84 # Default Interrupt Blanking parameters:
85 #
86 # rxdma-intr-time = 8;
87 # rxdma-intr-pkts = 32;
88 #
89 # To turn off interrupt blanking, use the minimum values for both
90 # rxdma-intr-time and rxdma-intr-pkts.
91 #
92 #
93 #------- Classification and Load Distribution Configuration ------
94 #
95 # class-opt-****-***
96 # These parameters define how each IP class is configured.
97 # They control how the flow template is constructed and how
98 # packets are distributed within RDC groups.
99 #
100 # supported classes:
101 # class-opt-ipv4-tcp class-opt-ipv4-udp class-opt-ipv4-sctp
102 # class-opt-ipv4-ah class-opt-ipv6-tcp class-opt-ipv6-udp
103 # class-opt-ipv6-sctp class-opt-ipv6-ah
104 #
105 # Configuration bits (Thes following bits will be decoded
106 # by the driver as hex format).
107 #
108 # 0010: use MAC Port (for flow key)
109 # 0020: use L2DA (for flow key)
110 # 0040: use VLAN (for flow key)
111 # 0080: use proto (for flow key)
112 # 0100: use IP src addr (for flow key)
113 # 0200: use IP dest addr (for flow key)
114 # 0400: use Src Port (for flow key)
115 # 0800: use Dest Port (for flow key)
116 #
117 # The following uses L2DA, VLAN, IP proto, IP src and dest and TCP
118 # src and dest port for computing the flow key for IPv4 TCP packets.
119 #
120 # class-opt-ipv4-tcp = 0xfe0;

122 #------- Software LSO (large segment offload) support --------
123 # To enable software LSO for all nxge interfaces,
124 #soft-lso-enable = 1;
125 #
126 # To disable software LSO for all nxge interfaces,
127 #soft-lso-enable = 0;
128 #
129 # Default software LSO is set to 0.
130 # Please refer to examples at the end of this file for
131 # enabling or disabling software LSO for a particular nxge interface.
132 #
133 #
134 # ------- How to set parameters for a particular interface --------
135 # The example below shows how to locate the device path and set a
136 # parameter for a particular nxge interface. (Using jumbo support as
137 # an example)
138 #
139 # Use the following command to find out the device paths for nxge,
140 # more /etc/path_to_inst | grep nxge
141 #
142 # For example, if you see,
143 # "/pci@7c0/pci@0/pci@8/network@0" 0 "nxge"
144 # "/pci@7c0/pci@0/pci@8/network@0,1" 1 "nxge"
145 # "/pci@7c0/pci@0/pci@8/network@0,2" 2 "nxge"
146 # "/pci@7c0/pci@0/pci@8/network@0,3" 3 "nxge"
147 #
148 # Use the above path_to_inst file as an example to enable software LSO
149 # for port 0 and 1, and disable software LSO for port 2 and 3.
150 #
151 # name = "pciex108e,abcd" parent = "/pci@7c0/pci@0/pci@8" unit-address = "0"
152 # soft-lso-enable = 1;
153 # name = "pciex108e,abcd" parent = "/pci@7c0/pci@0/pci@8" unit-address = "0,1"
154 # soft-lso-enable = 1;
155 # name = "pciex108e,abcd" parent = "/pci@7c0/pci@0/pci@8" unit-address = "0,2"
156 # soft-lso-enable = 0;
157 # name = "pciex108e,abcd" parent = "/pci@7c0/pci@0/pci@8" unit-address = "0,3"
158 # soft-lso-enable = 0;
159 #
160 #
161 # If the path_to_inst file is:
162 #
163 # "/niu@80/network@0" 0 "nxge"
164 # "/niu@80/network@1" 1 "nxge"
165 #
166 # Enable software lso for port 0, and disable software LSO for port 1
