r8152: re-schedule napi for tx

2017-06-17T04:39:38+00:00

[ Upstream commit 248b213ad908b88db15941202ef7cb7eb137c1a0 ]

Re-schedule napi after napi_complete() for tx, if it is necessay.

In r8152_poll(), if the tx is completed after tx_bottom() and before
napi_complete(), the scheduling of napi would be lost. Then, no
one handles the next tx until the next napi_schedule() is called.

sierra_net: Add support for IPv6 and Dual-Stack Link Sense Indications

2017-06-17T04:39:36+00:00

[ Upstream commit 5a70348e1187c5bf1cbd0ec51843f36befed1c2d ]

If a context is configured as dualstack ("IPv4v6"), the modem indicates
the context activation with a slightly different indication message.
The dual-stack indication omits the link_type (IPv4/v6) and adds
additional address fields.
IPv6 LSIs are identical to IPv4 LSIs, but have a different link type.

sierra_net: Skip validating irrelevant fields for IDLE LSIs

2017-06-17T04:39:36+00:00

[ Upstream commit 764895d3039e903dac3a70f219949efe43d036a0 ]

When the context is deactivated, the link_type is set to 0xff, which
triggers a warning message, and results in a wrong link status, as
the LSI is ignored.

[ Upstream commit 486181bcb3248e2f1977f4e69387a898234a4e1e ]

In their infinite wisdom, and never ending quest for end user frustration,
Lenovo has decided to use a new USB device ID for the wwan modules in
their 2017 laptops.  The actual hardware is still the Sierra Wireless
EM7455 or EM7430, depending on region.
