From: Tomasz Duszynski Date: Mon, 21 Jun 2021 15:04:33 +0000 (+0200) Subject: common/cnxk: add BPHY IRQ setup X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=81c7f0e42221a3fd00d77f54e09491b1fdf83259;p=dpdk.git common/cnxk: add BPHY IRQ setup Add support for initializing baseband PHY IRQs. While at it also add support for reverting back to the default state.
