Correct, this is in fact a bug. But IEP1 is also needed by HSR firmware so I thought of keeping this patch with HSR series. As HSR will be completely broken if IEP1 is not enabled. I didn't want to post two patches one as bug fix to net and one part of HSR to net-next thus I thought of keeping this patch in this series only. > What is the impact if IEP1 is not enabled for dual emac. > Without IEP1 enabled, Crash is seen on AM64x 10M link when connecting / disconnecting multiple times. On AM65x IEP1 was always enabled because `prueth->pdata.quirk_10m_link_issue` was true.

On AM65x IEP1 was always enabled because In that ase you need to enable quirk_10m_link_issue for AM64x platform.

You also need to add the Fixes tag. > Yes I understand that. The problem was I will need to send the patch twice once as bug fix to net/main, once as part of this series to net-next/main and drop it from this series once the patch gets merged to net and is synced to net-next. Since I cannot post this series without this patch as the HSR feature will get broken. Or I need to post this to net/main and wait for it to be part of net-next and then only I can re-post this series. So to avoid all these I thought of only posting it as part of this series. This is not a major bug and it will be okay from feature perspective if this bug gets merged via net-next. What do you suggest now? Should I post the bug fix to net/main and post this seires without this patch or wait for the bug fix to sync then only post this series? >> >>> What is the impact if IEP1 is not enabled for dual emac. >>> >> >> Without IEP1 enabled, Crash is seen on AM64x 10M link when connecting / >> disconnecting multiple times. On AM65x IEP1 was always enabled because > > In that ase you need to enable quirk_10m_link_issue for AM64x platform. Correct. But since for all ICSSG supported platform quirk_10m_link_issue needs to be enabled. Which in turn will enable IEP1. I think it's better enable IEP1 directly without any condition. IEP1 is also needed for Switch and HSR firmwares so I thought directly enabling it instead of enabling it inside the if check `prueth->pdata.quirk_10m_link_issue` would be better idea. What do you suggest here? Will setting `quirk_10m_link_issue` as true for AM64x will be a better approach or always enabling IEP1 without any if check will be better approach for this? > I understand that IEP1 is not required for 100M/1G. > >> `prueth->pdata.quirk_10m_link_issue` was true.

I would suggest that you first send a bug fix patch for AM64x which sets quirk_10m_link_issue for AM64x. This should make it into the next -rc and eventually stable. Then in your HSR series, you can decide if you want to conditionally enable it for HSR/switch mode or permanently enable it regardless. > >> I understand that IEP1 is not required for 100M/1G. >> >>> `prueth->pdata.quirk_10m_link_issue` was true.
