[OpenWrt-Devel] [PATCH][ar71xx] Routerboard 951G Switch Fix

[Baptiste Jonglez]

Hi,

Sorry to bump up the thread again.  Is there anything blocking to merge
this patch?

If it helps, there are user reports about setting different values of
ath79_eth0_pll_data.pll_1000 here:

  https://wiki.openwrt.org/toh/mikrotik/rb2011uias#tracking_reported_experience_with_suggested_patch_for_the_5_gige_ports

Thanks,
Baptiste
