Commit f6988cb63a ("team: don't call netdev_change_features under
team->lock") fixed the issue calling netdev_change_features under
team->lock for team_compute_features.
But there are still two places where it calls netdev_change_features
under team->lock, team_port_add and team_port_del. It may cause a
dead lock when the slave port with LRO enabled is added.
This patch is to fix this dead lock by moving netdev_change_features
out of team_port_add and team_port_del, and call it after unlocking
the team lock.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
