Subject: Re: [PATCH net] net: wwan: Fix MRU mismatch issue which may lead to
 data connection lost

> In pci_generic.c there is a 'mru_default' in struct mhi_pci_dev_info.
> This value shall be used for whole mhi if it's given a value for a specific product.
> But in function mhi_net_rx_refill_work(), it's still using hard code value MHI_DEFAULT_MRU.
> 'mru_default' shall have higher priority than MHI_DEFAULT_MRU.
> And after checking, this change could help fix a data connection lost issue.
