1. The pcie&qmi_wwan_q driver is common to all Linux systems
2. Pcie&qmi _wwan_q driver supports the hardware acceleration function of IPQ. 
Before enabling the hardware acceleration function of IPQ, it is necessary to 
confirm whether the IPQ chip and software version can support the hardware acceleration 
(it can be confirmed to qualcomm IPQ). Only when the hardware acceleration is supported, 
can the driver hardware acceleration function be effective

3. Enabling hardware acceleration requires qca-nss-drv code, which needs to be coded into the system
4. The file rmnet_nss.c needs to be included when enabling the hardware to speed up compilation. 
At present, the file provided in the driver package is in our own IPQ system, and the client needs to 
replace rmnet_nss.c to its own IPQ system when porting. The reference path of rmnet_nss.c is as follows: 

QSDK /qca/ SRC /data-kernel/drivers/rmnet-nss/rmnet_nss.c

5. The enable hardware acceleration function needs to specify the header file path of the qca-nss-drv code, 
otherwise, there will be an error when compiling the header file, the header file path reference is as follows: 

$(STAGING_DIR)/usr/include/qca-nss-drv
