[dpdk-stable] patch 'raw/ifpga/base: fix SPI transaction' has been queued to stable release 19.11.4

[luca.boccassi at gmail.com]

Hi,

FYI, your patch has been queued to stable release 19.11.4

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 07/26/20. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Thanks.

Luca Boccassi

Subject: [PATCH] raw/ifpga/base: fix SPI transaction

[ upstream commit 6f583cd8b01b5b6568668ce8efb78d3eaaa55b61 ]

0x4a means idle status on physical layer. when encounter
0x4a on raw data, it need insert a ESCAPE character for
indication.

Fixes: 96ebfcf8 ("raw/ifpga/base: add SPI and MAX10 device driver")
