From bcd5abe28f40cc6a935d3339cde27976f6be3f1a Mon Sep 17 00:00:00 2001 From: Russ Gorby Date: Thu, 16 Jun 2011 14:20:12 -0700 Subject: tty: n_gsm: Add raw-ip support This patch adds the ability to open a network data connection over a mux virtual tty channel. This is for modems that support data connections with raw IP frames instead of PPP. On high speed data connections this eliminates a significant amount of PPP overhead. To use this interface, the application must first tell the modem to open a network connection on a virtual tty. Once that has been accomplished, the app will issue an IOCTL on that virtual tty to create the network interface. The IOCTL will return the index of the interface created. The two IOCTL commands are: ioctl( fd, GSMIOC_ENABLE_NET ); ioctl( fd, GSMIOC_DISABLE_NET ); Signed-off-by: Russ Gorby Acked-by: Alan Cox Signed-off-by: Greg Kroah-Hartman --- include/linux/gsmmux.h | 11 +++++++++++ 1 file changed, 11 insertions(+) (limited to 'include/linux/gsmmux.h') diff --git a/include/linux/gsmmux.h b/include/linux/gsmmux.h index 378de4195caf..c25e9477f7c3 100644 --- a/include/linux/gsmmux.h +++ b/include/linux/gsmmux.h @@ -21,5 +21,16 @@ struct gsm_config #define GSMIOC_GETCONF _IOR('G', 0, struct gsm_config) #define GSMIOC_SETCONF _IOW('G', 1, struct gsm_config) +struct gsm_netconfig { + unsigned int adaption; /* Adaption to use in network mode */ + unsigned short protocol;/* Protocol to use - only ETH_P_IP supported */ + unsigned short unused2; + char if_name[IFNAMSIZ]; /* interface name format string */ + __u8 unused[28]; /* For future use */ +}; + +#define GSMIOC_ENABLE_NET _IOW('G', 2, struct gsm_netconfig) +#define GSMIOC_DISABLE_NET _IO('G', 3) + #endif -- cgit v1.2.3
