X-Git-Tag: v22.02-rc0~214
X-Git-Url: https://gerrit.fd.io/r/gitweb?a=commitdiff_plain;h=e3ef3f6aea261c4b1a8d599cc1e76cbe8a4a670f;p=vpp.git

dpdk: add base-virtaddr config option

Type: improvement

Allow the use of the base-virtaddr config option to be passed through
to DPDK. This is useful to allow use of devices with an IOMMU in
nested VMs without resorting to PA IOVA mode.
