      tty: n_gsm: Added refcount usage to gsm_mux and gsm_dlci structs · 6ab8fba7
      由 Russ Gorby 提交于 
      The gsm_mux is created/destroyed when ldisc is
opened/closed but clients of the MUX channel devices (gsmttyN)
may access this structure as long as the TTYs are open.
For the open, the ldisc open is guaranteed to preceed the TTY open,
but the close has no such guaranteed ordering. As a result,
the gsm_mux can be freed in the ldisc close before being accessed
by one of the TTY clients. This can happen if the ldisc is removed
while there are open, active MUX channels.
A similar situation exists for DLCI-0, it is basically a resource
shared by MUX and DLCI  , and should not be freed while they can
be accessed

To avoid this, gsm_mux and dlcis now have a reference counter
ldisc open takes a reference on the mux and all the dlcis
gsmtty_open takes a reference on the mux, dlci0 and its specific
dlci. Dropping the last reference initiates the actual free.

      tty: n_gsm: Add raw-ip support · bcd5abe2
      由 Russ Gorby 提交于 
      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 );

      tty: n_gsm: expose gsmtty device nodes at ldisc open time · d50f6dca
      由 Russ Gorby 提交于 
      The n_gsm driver being an ldisc, does not provide a convenient method
e.g. udev to create the tty device nodes automatically when the ldisc
is opened.

The TTY device nodes are now created via calls to tty_register_device
from the ldisc open.

      pch_phub: Fix register miss-setting issue · 20ae6d0b
      由 Tomoya MORINAGA 提交于 
      Register "interrupt delay value" is for GbE which is connected to Bus-m of PCIe.
However currently, the value is set for Bus-n.
As a result, the value is not set correctly.
This patch moves setting the value processing of Bus-n to Bus-m.
