Subject: realtek: add RTL821X_CHIP_ID
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=a9781a04a1868e5321a360e636290fb058e7477a;p=openwrt%2Fstaging%2Fblogic.git

realtek: add RTL821X_CHIP_ID

According to the Realtek SDK code, the RTL8214FC, RTL8218B and RTL8218FB
all have the same chip ID 0x6276. Let's add a constant for it, as we're
using it in more than one location.
