From: Qi Zhang Date: Thu, 29 Aug 2019 02:35:56 +0000 (+0800) Subject: net/ice/base: support NVM rollback detection X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=5b674b57e79a20424f941fce02fce9580b22424e;p=dpdk.git net/ice/base: support NVM rollback detection This patch adds code to detect NVM rollback. The rollback detection is done as part of the HW init flow. When NVM rollback is detected, a warning message is printed along with the FW/NVM version data. To do this, this patch adds a helper function ice_get_nvm_version. Also, a pointer to hw->nvm is already available in ice_init_nvm. Just use this instead of &hw->nvm.
