N3150機配Realtek LAN，響FreeBSD/pfSense真係災難

我部n3150之前都講過。

早排認真試部N3150, iperf3太低而且成日唔穩定，開頭以為係hardware failure，但換咗返黎問題都係一樣，就懷疑係咪Realtek夾FreeBSD有問題....一試，死火。

Realtek GbE配pfSense 2.2.6, 可以見到斷traffic，console顯示直頭熄port顯示"re0: watchdog timeout"


Realtek GbE配Ubuntu 16.04 Linux，冇斷traffic一直打爆GbE port


鬼佬一樣有同樣問題: https://forums.freenas.org/index ... .24052/#post-147189
The bigger problems with Realtek and Atheros are not throughput (although some do hate the poor throughput). The problems are that they randomly just stop working. People will take 80MB/sec over 0MB/sec any day.
FreeNAS一樣係FreeBSD，同一命運。

FreeBSD 10.2一樣死法，一樣n3150 https://forums.freebsd.org/threads/55861/
However, the network has been very unstable with poor throughput and many NIC driver restarts (ie, "re0: watchdog timeout"). It has no expansion slots, so a replacement NIC is not an option.

最慘係，我試埋所有FreeBSD tunable，亦試埋pfSense 2.3，一樣死。

由於我要行VPN，要快嘅OpenVPN同IPSec，好需要AES-NI又好想用pfSense，所以解決方法係扯個mini PCI-e出黎拉Intel卡，之後再貼安裝過程上黎。

如果各位打算行Linux/Windows的話，Realtek都算正常用得，要用pfSense行n3150賺AES-NI的話，我建議大家買塊有3條PCI-E槽嘅n3150板 (x16 + x1 + x1)，再配返Intel多port卡免麻煩。

Realtek? No way.

想請教點樣扯個mini PCI-e出黎拉Intel卡?

mini-pcie lan card or mini-pcie to pcie adapter

唉，我嗰時又係間唔屎 watchdog timeout, 搞到用 clearOS, 原來係 realtek 唔夾，但係好似係新 pfsense version 先係咁，以前 version 我用過好似冇呢個問題。。？

mini-pcie to pcie adapter 要另外配12V去供電

我由2.2用到2.2.6都有咁既問題
Realtak同FreeBSD有咁既問題架
我個opt1係realtek 8111g
開左controlflow好左好多無出咁多re0: watchdog timeout
呀, 好似仲要加幾句code
你都試試

唔緊要啦本來部機就有12V input, 分多個出黎。

試過flow control冇用, Half-duplex就有但會跌速至500Mbps。果幾句loader tunables都係冇效果......
有時間我試下FreeBSD 11果個新driver同埋Realtek official driver，有改善就考慮下back ports

差 d 想去淘占美 N3150 玩 pfsense, 要觀察下先

認真，Realtek 既卡從來都無真係係 *nix 好過架喎
