[PATCH 3.14 06/35] PCI: Limit config space size for Netronome NFP6000 family

Show all headers | View raw

3.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jason S. McMullan <jason.mcmullan@netronome.com>

commit 9f33a2ae59f24452c1076749deb615bccd435ca9 upstream.

The NFP6000 has an erratum where reading/writing to PCI config space
addresses above 0x600 can cause the NFP to generate PCIe completion
timeouts.

Limit the NFP6000's config space size to 0x600 bytes.
