+.Sh NAME
+.Nm bxe
+.Nd "Broadcom BCM57710/BCM57711/BCM57711E 10Gb Ethernet adapter driver"
+.Sh SYNOPSIS
+To compile this driver into the kernel,
+place the following lines in your
+kernel configuration file:
+.Bd -ragged -offset indent
+.Cd "device bxe"
+.Ed
+.Pp
+Alternatively, to load the driver as a
+module at boot time, place the following line in
+.Xr loader.conf 5 :
+.Bd -literal -offset indent
+if_bxe_load="YES"
+.Ed
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for PCIe 10GbE Ethernet adapters based on
+BCM5771x chips.
+The driver supports Jumbo Frames, VLAN tagging, IP, UDP and TCP checksum
+offload, MSI-X, TCP Segmentation Offload (TSO), Large Receive Offload (LRO),
+and Receive Side Steering (RSS).
+.Pp
+For more information on configuring this device, see
+.Xr ifconfig 8 .
+.Sh HARDWARE
+The
+.Nm
+driver provides support for various NICs based on the Broadcom BCM5771x
+family of 10GbE Ethernet controller chips, including the
+following:
+.Pp
+.Bl -bullet -compact
+.It
+Broadcom NetXtreme II BCM57710 10GbE
+.It
+Broadcom NetXtreme II BCM57711 10GbE
+.It
+Broadcom NetXtreme II BCM57711E 10GbE
+.El
+.Sh SYSCTL VARIABLES
+The following variables are available as both
+.Xr sysctl 8
+variables and
+.Xr loader 8
+tunables:
+.Bl -tag -width indent
+.It Va hw.bxe.dcc_enable
+Enable HP Flex-10 support.
+Allowed values are 0 to disable and 1 to enable.
+The default value is 0.
+.It Va hw.bxe.tso_enable
+Enable TCP Segmentation Offload.
+The default value is 1.
+.It Va hw.bxe.int_mode
+Set interrupt mode.
+Allowed values are 0 for IRQ, 1 for MSI/IRQ and 2 for MSI-X/MSI/IRQ.
+The default value is 2.
+.It Va hw.bxe.queue_count
+Specify the number of queues that will be used when a multi-queue
+RSS mode is selected using bxe_multi_mode.
+Allowed values are 0 for Auto or 1 to 16 for fixed number of queues.
+The default value is 0.
+.It Va hw.bxe.multi_mode
+Enable Receive Side Steering.
+Allowed values are 0, which disables all multi-queue/packet sorting
+algorithms, and 1, which assigns incoming frames to receive queues
+according to RSS.
+The default value is 0.
+.It Va hw.bxe.rx_ticks
+Control interrupt coalescing for received frames.
+The first frame always causes an interrupt, but subsequent frames
+are coalesced until the RX/TX ticks timer value expires and another
+interrupt occurs.
+The default value is 25.
+.It Va hw.bxe.tx_ticks
+Control interrupt coalescing for trasmitted frames.
+The first frame always causes an interrupt, but subsequent frames
+are coalesced until the RX/TX ticks timer value expires and another
+interrupt occurs.
+The default value is 50.
+.It Va hw.bxe.mrrs
+Allows to set the PCIe maximum read request size.
+Allowed values are -1 for Auto, 0 for 128B, 1 for 256B, 2 for 512B,
+and 3 for 1kB.
+The default value is -1.
