rge: add the Intel Killer E5000 PCI ID

2026-05-11T15:26:03Z

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. Tested by: "Sinetek" on Discord Reviewed by: adrian Differential Revision: https://reviews.freebsd.org/D56917

rge: add disable_aspm tunable for PCIe power management

2026-04-17T02:34:55Z

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). Signed-off-by: Christos Longros Reviewed by: adrian Differential Revision: https://reviews.freebsd.org/D56103

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

2026-04-10T17:31:38Z

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.

rge: make rx_process_limit a sysctl tunable

2026-03-25T01:27:14Z

The number of packets processed per interrupt was hardcoded to 16. Add a per-interface sysctl dev.rge.%d.rx_process_limit tunable so users can adjust this value at runtime. Signed-off-by: Christos Longros Reviewed by: ziaee, adrian Differential Revision: https://reviews.freebsd.org/D56014

rge: use C style comments instead of C++

2026-03-15T20:10:59Z

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 */. Signed-off-by: Christos Longros Reviewed by: adrian Differential Revision: https://reviews.freebsd.org/D55743

rge: log silicon revision during attach

2026-02-22T18:07:37Z

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.
