34 To compile this driver into the kernel,
35 place the following lines in your
36 kernel configuration file:
37 .Bd -ragged -offset indent
41 Alternatively, to load the driver as a
42 module at boot time, place the following line in
44 .Bd -literal -offset indent
50 driver provides support for PCIe 10GbE Ethernet adapters based on
52 The driver supports Jumbo Frames, VLAN tagging, IP, UDP and TCP checksum
53 offload, MSI-X, TCP Segmentation Offload (TSO), Large Receive Offload (LRO),
54 and Receive Side Steering (RSS).
56 For more information on configuring this device, see
61 driver provides support for various NICs based on the Broadcom BCM5771x
62 family of 10GbE Ethernet controller chips, including the
67 Broadcom NetXtreme II BCM57710 10GbE
69 Broadcom NetXtreme II BCM57711 10GbE
71 Broadcom NetXtreme II BCM57711E 10GbE
74 The following variables are available as both
79 .Bl -tag -width indent
80 .It Va hw.bxe.dcc_enable
81 Enable HP Flex-10 support.
82 Allowed values are 0 to disable and 1 to enable.
83 The default value is 0.
84 .It Va hw.bxe.tso_enable
85 Enable TCP Segmentation Offload.
86 The default value is 1.
87 .It Va hw.bxe.int_mode
89 Allowed values are 0 for IRQ, 1 for MSI/IRQ and 2 for MSI-X/MSI/IRQ.
90 The default value is 2.
91 .It Va hw.bxe.queue_count
92 Specify the number of queues that will be used when a multi-queue
93 RSS mode is selected using bxe_multi_mode.
94 Allowed values are 0 for Auto or 1 to 16 for fixed number of queues.
95 The default value is 0.
96 .It Va hw.bxe.multi_mode
97 Enable Receive Side Steering.
98 Allowed values are 0, which disables all multi-queue/packet sorting
99 algorithms, and 1, which assigns incoming frames to receive queues
101 The default value is 0.
102 .It Va hw.bxe.rx_ticks
103 Control interrupt coalescing for received frames.
104 The first frame always causes an interrupt, but subsequent frames
105 are coalesced until the RX/TX ticks timer value expires and another
107 The default value is 25.
108 .It Va hw.bxe.tx_ticks
109 Control interrupt coalescing for trasmitted frames.
110 The first frame always causes an interrupt, but subsequent frames
111 are coalesced until the RX/TX ticks timer value expires and another
113 The default value is 50.
115 Allows to set the PCIe maximum read request size.
116 Allowed values are -1 for Auto, 0 for 128B, 1 for 256B, 2 for 512B,
118 The default value is -1.
