rge: fix multicast add/removal by using if_getdrvflags()

2026-07-12T15:26:46+00:00

Using if_getflags() to check IFF_DRV_RUNNING is wrong;
if_getdrvflags() is required.  This issue resulted in the
multicast filter not being updated.

This was an oversight by me in my initial port.

Thanks to danilo@ for reporting it and Oleg 
for the fix.

rge: Fix 32-bit powerpc build

2026-07-01T02:41:56+00:00

Book-E powerpc has 64-bit bus_addr_t but only a 32-bit bus_size_t.  Use
the right macros for maxsize and maxsegsize to fix the build.

rge: add the Intel Killer E5000 PCI ID

2026-05-11T15:26:03+00:00

This and the E3000 are both handled by the r8169 driver in Linux, and
reportedly this is infact just a straight re-brand of the RTL8126.

rge: add disable_aspm tunable for PCIe power management

2026-04-17T02:34:55+00:00

Add a per-interface loader tunable dev.rge.%d.disable_aspm to
disable PCIe ASPM (L0s/L1) and ECPM on the RTL8125/8126/8127.

Disabling ASPM reduces latency at the cost of higher power
consumption. Default is off (ASPM left as configured by BIOS).

rge: add Wake-on-LAN support for magic packet

2026-04-10T17:31:38+00:00

Advertise IFCAP_WOL_MAGIC when PCI power management is available
and enable it by default.  On suspend or shutdown, rge_setwol()
enables the WOL_MAGIC and WOL_LANWAKE bits in CFG3/CFG5, disables
the RXDV gate, and enables PM so the NIC stays powered to watch
for magic packets.

Move hardware-specific WOL register configuration into
rge_wol_config() in if_rge_hw.c to keep hardware-specific
functions in sync with OpenBSD.

Update rge.4 to document WoL support.

Tested on FreeBSD 16.0-CURRENT bare metal with Realtek RTL8125
on a Gigabyte B650 Gaming X AX motherboard.

Add a per-interface sysctl dev.rge.%d.rx_process_limit tunable so

rge: use C style comments instead of C++

2026-03-15T20:10:59+00:00

FreeBSD style(9) mandates C style comments. The initial import from
OpenBSD left several C++ style // comments in if_rge.c and if_rgevar.h.
Replace them with proper /* */ comments.

Also fix a malformed comment that mixed // with a closing */.

rge: log silicon revision during attach

2026-02-22T18:07:37+00:00

The initial import from OpenBSD contained chip revision printf() calls
commented out, as OpenBSD's bare printf() style does not translate to
FreeBSD's device_printf() idiom. The result is that users cannot
distinguish RTL8125 from RTL8125B, RTL8125D_1, RTL8125D_2 etc. via
dmesg alone, even though all variants show as '' from the PCI
probe string.

Add proper device_printf() calls including the raw hwrev value,
consistent with how re(4) reports chip revisions.
