Message-Id: <20231005170110.3221306-2-anthony.l.nguyen@intel.com> Date: Thu, 5 Oct 2023 10:01:06 -0700 From: Tony Nguyen <anthony.l.nguyen@...el.com> To: davem@...emloft.net, kuba@...nel.org, pabeni@...hat.com, edumazet@...gle.com, netdev@...r.kernel.org Cc: Paul M Stillwell Jr <paul.m.stillwell.jr@...el.com>, anthony.l.nguyen@...el.com, jacob.e.keller@...el.com, vaishnavi.tipireddy@...el.com, horms@...nel.org, leon@...nel.org, Pucha Himasekhar Reddy <himasekharx.reddy.pucha@...el.com> Subject: [PATCH net-next v4 1/5] ice: remove FW logging code From: Paul M Stillwell Jr <paul.m.stillwell.jr@...el.com> The FW logging code doesn't work because there is no way to set cq_ena or uart_ena so remove the code. This code is the original (v1) way of FW logging so it should be replaced with the v2 way.
