Official Realtek Driver Binary 1.95 For 2.4.4 Release

whosmatt

I have a bunch of HP motherboards that have them:

re0@pci0:3:0:0: class=0x020000 card=0x2b05103c chip=0x813610ec rev=0x07 hdr=0x00
    vendor     = 'Realtek Semiconductor Co., Ltd.'
    device     = 'RTL810xE PCI Express Fast Ethernet controller'
    class      = network
    subclass   = ethernet

I don't currently use this interface with my pfSense box but I did for a while and it was fine with the driver that ships with pfSense. By "fine" I mean it wasn't obviously broken in any way.

I just updated it and it really increases the software performance very well. Thank you very much for this contribution, it is very appreciated.

@pereirara24 do you still have to check the box ofr the three options below in system advanced networking:
Disable hardware chekcsum offload
Disable hardware tcp segmentation offload
Disable hardware large received offload

I am running stock now and my box hangs when i do large transfer over the network sometimes

Thank you.

@steeletanner I would say yes.

Yes, I would disable all hardware offloading if you're seeing an issue.

Do you see anything logged when this happens? Any sort of crash report when you reboot?

Using this driver for months on 2.4.4 without problems. Now, after upgrade to 2.4.5 I'm getting lots of errors with driver loaded. Without driver loaded, the troughput TO firewall is only around 580mbit but no errors. Traffic FROM firewall is round about 970 mbit. Generating traffic with iperf Server on pfSense. Using the compiled driver version for FreeBSD 11.3 as postet above.

I'm using VLAN on LAN. WAN interface is free of errors.

Any ideas? Disabled hardware checksum offloading without effect.

@TheNarc Thank you so much. I was about to replace my Qotom N3150 based firewall as, much like others, on recent releases of pfsense the nics would just stop responding under high load. Fingers crossed this fixes it.

I have one of these Qotom N3150 and I have never had any issues since updating the drivers over 12 months ago. It just keeps 'trucking' along and only gets rebooted for an update.

Driver if_re.ko no longer ,loaded on pfSense 2.4.5-p1, worked fine on versions before.

Error in dmesg on kldload -nv /boot/kernel/if_re.ko
KLD if_re.ko: depends on kernel - not available or version mismatch
linker_load_file: Unsupported file type

Just checked my dmesg and did not find any errors related to if_re.ko in 2.4.5-p1.

@gregeeh

Is the driver loaded for you, shown in kldstat?

For me it is not loaded on boot with no error shown in dmesg either. The error is only after manual try with kldload.

[Solved]
Recompiled driver for me on latest 11.3-RELEASE. Now works again.

@wkn Do you mind uploading the compiled ko driver for 2.4.5.p1 ?
Thanks

@netblues

Of course, here it is...

@whosmatt I thought I was fine as well. I took a closer look for errors and they were there. I replaced the driver and they were gone.

my problems still persists. only around 700mbit/sec with iperf (client<->firewall on the same interface) and massiv errors on all vlan interfaces. Even with 2.4.5-p1 :-(

Board: Gigabyte J3455N-D3H

Edit: testing around with same board but with and without vlan.

VLAN
iperf: pfS sending: 700 mbit
iperf: pfS receivig: 980 mbit
errors: massiv

without VLAN:
iperf: pfS sending: 680 mbit
iperf: pfS receiving: 970 mbit
errors: NONE

seems like an issue with vlans.

@tpf check your cpu / ram usage just
In case

This is very strange and it seems that the errors are cosmetic.
There is no degradation in speed/througput
If errors are massive, performance would suffer dearly.

Thank you!

cpu und ram are inconspicuous.

Hmmm. There are some retries in iperf. I have to benchmark with some parameters changed. Errors are only OUT errors. IN direction is OK.

netblues

@tpf Indeed. I also see that.
It seems to be vlan and realtek related. I see that my realtek ( RTL8111/8168/8411) has support for hardware vlan tagging.
Running iperf3 outbound on a realtec usb interface without vlans doesn't have retries...

Hi.
I am new in pfsense. Got trouble with realtek down interface on PC. I install custom driver for 2.4.5 p1. kldstat show it. Will test system now. I also have a question about security of this custom driver and some possible backdoors in it. Can it be used to go arround firewall rules?

And second question is about folder /boot/kernel - in 2.4.5 p1 it looks like that folder not exist. By test i found that system has folder bootpool/kernel - i did use it and it works fine - kldstat show my driver. Did i use correct folder for driver?
And again i am new in freebsd and pfsense maybe i don't know some stuff. Thanks you.
