Subject: kernel: rtl8367b: use id as a bit offset for BYPASS_LINE_RATE
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=817e1323322c9d58464330a15994e8693b48b9c5;p=openwrt%2Fstaging%2Fxback.git

kernel: rtl8367b: use id as a bit offset for BYPASS_LINE_RATE

In RTL8367B (RTL8367RB/RTL8367R-VB), the driver in GPL tars of the
devices with this switch directly uses the ID of external interface
as a bit offset.

We should use the same way.

ref (RTL8367B):
  - ASUS RT-N56U
  - TP-Link Archer C2 v1

ref (RTL8367):
  - TP-Link TL-WR2543ND v1
