    rtw89: update Realtek's rtw89 driver.
    
    This adds support for the Realtek 8922AE PCI
    wireless network (Wi-Fi 7) adapter.
    
    This version is based on

 +.Sh NAME
 +.Nm rtw89
 +.Nd Realtek IEEE 802.11ax wireless network driver
 +.Sh SYNOPSIS
 +The driver will auto-load without any user interaction using
 +.Xr devmatch 8
 +if enabled in
 +.Xr rc.conf 5 .
 +.Pp
 +Only if auto-loading is explicitly disabled, place the following
 +lines in
 +.Xr rc.conf 5
 +to manually load the driver as a module at boot time:
 +.Bd -literal -offset indent
 +kld_list="${kld_list} if_rtw89"
 +.Ed
 +.Pp
 +It is discouraged to load the driver from
 +.Xr loader 8 .
 +.Sh DESCRIPTION
 +The
 +.Nm
 +driver is derived from Realtek's Linux rtw89 driver.
 +.Pp
 +This driver requires firmware to be loaded before it will work.
 +The package
 +.Pa wifi-firmware-rtw89-kmod
 +from the
 +.Pa ports/net/wifi-firmware-rtw89-kmod
 +port needs to be installed before the driver is loaded.
 +Otherwise no
 +.Xr wlan 4
 +interface can be created using
 +.Xr ifconfig 8 .
 +One should use
 +.Xr fwget 8
 +to install the correct firmware package.
 +.Pp
 +The driver uses the
 +.\" No LinuxKPI man pages so no .Xr here.
 +.Em linuxkpi_wlan
 +and
 +.Em linuxkpi
 +compat framework to bridge between the Linux and
 +native
 +.Fx
 +driver code as well as to the native
 +.Xr net80211 4
 +wireless stack.
 +.Pp
 +While
 +.Nm
 +supports all 802.11 a/b/g/n/ac and ax
 +the compatibility code currently only supports 802.11 a/b/g modes.
 +Support for 802.11 n/ac is to come.
 +.Sh LOADER TUNABLES
 +.Bl -tag -width indent
 +.It Va compat.linuxkpi.skb.mem_limit
 +If you are running a 64bit system with more than 4GB of main memory
 +you need to set this tunable to
 +.Sy 1
 +in
 +.Xr loader.conf 5
 +and reboot once to make it effective.
 +This tunable will work around a problem with DMA and limit allocations
 +for network buffer memory to the lower 32bit of physical memory and
 +make the driver work.
 +.El
 +.Sh HARDWARE
 +The
 +.Nm
 +driver supports PCIe devices with the following chipsets:
 +.Pp
 +.Bl -tag -width Ds -offset indent -compact

++.It Realtek 8852CE Wi-Fi 6E (RTL8852CE)
++.It Realtek 8922AE Wi-Fi 7  (RTL8922AE)
 +.El
 +.Sh BUGS
 +Certainly.
 +.Pp
 +Does not seem to work (reliably) on machines with more than 4GB of
 +main memory.
 +See in the
 +.Sx LOADER TUNABLES
 +section above.
 +.Sh SEE ALSO
 +.Xr wlan 4 ,
 +.Xr fwget 8 ,
 +.Xr ifconfig 8 ,
 +.Xr wpa_supplicant 8
 +.Sh HISTORY
 +The
 +.Nm
 +driver first appeared in
 +.Fx 14.2 .
