net: qmi_wwan: increase max QMI message size to 4096
QMI requests exceeding 1500 bytes are possible and device firmware does not handle fragmented messages very well. It is therefore necessary to increase the maximum message size from the current 512 bytes. The protocol message size limit is not documented in any publicly known source, but the out of tree driver from CodeAurora use 4 kB. This is therefore chosen as the new arbitrary default until the real limit is known. This should allow any QMI message to be transmitted without fragmentation, fixing known issues with GPS assistance data upload. Signed-off-by: Bjørn Mork <bjorn@mork.no> Signed-off-by: David S.
