This change adds support for TSO of MPLS packets. In my tests with tcpdump it seems to work. Note this test setup has a 9000 byte MTU: MPLS (label 100, exp 0, [S], ttl 64) IP srcip.50086 > dstip.1234: Flags [P.], seq 593345:644401, ack 0, win 420, options [nop,nop,TS val 45022534 ecr 1722291395], length 51056 IP dstip.1234 > srcip.50086: Flags [.], ack 593345, win 122, options [nop,nop,TS val 1722291395 ecr 45022534], length 0 IP dstip.1234 > srcip.50086: Flags [.], ack 602289, win 105, options [nop,nop,TS val 1722291395 ecr 45022534], length 0 IP dstip.1234 > srcip.50086: Flags [.], ack 620177, win 71, options [nop,nop,TS val 1722291395 ecr 45022534], length 0 MPLS (label 100, exp 0, [S], ttl 64) IP srcip.50086 > dstip.1234: Flags [P.], seq 644401:655953, ack 0, win 420, options [nop,nop,TS val 45022534 ecr 1722291395], length 11552 IP dstip.1234 > srcip.50086: Flags [.], ack 638065, win 37, options [nop,nop,TS val 1722291395 ecr 45022534], length 0 IP dstip.1234 > srcip.50086: Flags [.], ack 644401, win 25, options [nop,nop,TS val 1722291395 ecr 45022534], length 0 IP dstip.1234 > srcip.50086: Flags [.], ack 653345, win 8, options [nop,nop,TS val 1722291395 ecr 45022534], length 0 IP dstip.1234 > srcip.50086: Flags [.], ack 655953, win 3, options [nop,nop,TS val 1722291395 ecr 45022534], length 0 Signed-off-by: Joe Damato <jdamato@fastly.com> Co-developed-by: Mike Gallo <mgallo@fastly.com> Signed-off-by: Mike Gallo <mgallo@fastly.com> Tested-by: Gurucharan <gurucharanx.g@intel.com> (A Contingent worker at Intel) Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
