Also, the correct fixes tag should be the one added the Foxconn modem support, precisely "aac426562f56". One more thing, please make sure this MRU value works well for other Foxconn modems supported by this config. > Signed-off-by: Slark Xiao <slark_xiao@163.com> You should have added my Reviewed-by tag too...

BTW, I want to add this mru_default to cinterion-mv31 PRODUCT. Shall I use v3 or create a new version for that? It's confirmed that this change could help fix issue on that product. >> Signed-off-by: Slark Xiao <slark_xiao@163.com> > >You should have added my Reviewed-by tag too...
