Subject: Re: Is this 32-bit NCM?
Kevin - it works! the key seems to be in the tx_fixup function; there is a
special handling for frames effectively.
Please ... help me backport those changes to the standard Linux driver - it
will be a gain for us all, and in general you'll have a more probable
maintenance than you would with the driver from huawei.
Sorry huawei guys - I respect you, but there is a reason if drivers needs some
modifications to get merged. Hoping not to sound arrogant, my intent was only
to be clear.
