Subject: brcm63xx: reduce the number of Ethernet DMA channels from 16 to 8
X-Git-Tag: reboot~10189
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=4ef56823e09065e292b7ab33b8eef8ac0d919e41;p=openwrt%2Fopenwrt.git

brcm63xx: reduce the number of Ethernet DMA channels from 16 to 8

We currently used 16 DMA Ethernet channels, but the hardware only
supports up to 8 (with 2 per enet and the remaining for USB slave).
