+#ifndef _SOC_QCOM_RMNET_H_
+#define _SOC_QCOM_RMNET_H_
+
+#include <linux/types.h>
+
+/* Header structure that precedes packets in ETH_P_MAP protocol */
+struct rmnet_map_header {
+ u8 pad_len : 6;
+ u8 reserved_bit : 1;
+ u8 cd_bit : 1;
+ u8 mux_id;
+ __be16 pkt_len;
+} __aligned(1);

If we move this into include/soc/, I want the structure to be portable,
and avoid the bit fields. Please use mask/shift operations or the
include/linux/bits.h macros instead to make this work with big-endian
kernels.

Sure, I'll do that. I did that everywhere else in the driver,
but here I just tried to preserve the original code as I moved
it. I will update at least these structures, and all existing
code (plus the IPA code) to use fields masks.

Hi Alex

Could we instead have the rmnet header definition in
include/linux/if_rmnet.h
