Function i40e_init_shared_code

dpdk/drivers/net/i40e/base/i40e_common.c:991–1036

* i40e_init_shared_code - Initialize the shared code * @hw: pointer to hardware structure * * This assigns the MAC type and PHY code and inits the NVM. * Does not touch the hardware. This function must be called prior to any * other function in the shared code. The i40e_hw structure should be * memset to 0 prior to calling this function. The following fields in * hw structure should be fil

 * subsystem_vendor_id, and revision_id
