Subject: [PATCH net-next v4 0/2] adjust MTU as indicated by MBIM extended functional descriptor
Date: Wed, 19 Mar 2014 14:00:04 -0700 [thread overview]
Message-ID: <1395262806-19237-1-git-send-email-benchan@chromium.org> (raw)
The MBIM extended functional descriptor, defined in "Universal Serial Bus
Communications Class Subclass Specification for Mobile Broadband Interface
Model, Revision 1.0, Errata-1" by USB-IF, indicates the operator preferred MTU
value via a wMTU field.
This patch set ensures that the initial MTU value set by cdc_ncm on a MBIM net
device does not exceed the wMTU value, provided the MBIM device exposes a MBIM
extended functional descriptor.
* Changelog
v2: Fixed a le16_to_cpu conversion issue in patch 2/2 pointed out by
