Subject: mlx4: Replace PCI pool old API
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=b9f761aa78126d0937f6ab38d04aec4f9fcce1df;p=openwrt%2Fstaging%2Fblogic.git

mlx4: Replace PCI pool old API

The PCI pool API is deprecated. This commit replaces the PCI pool old
API by the appropriate function with the DMA pool API.
