![]() The i40e_asq_send_command will now use a non blocking usleep_range if possible (non-atomic context), instead of busy-waiting udelay. The usleep_range function uses hrtimers to provide better performance and removes the negative impact of busy-waiting in time-critical environments. 1. Rename i40e_asq_send_command to i40e_asq_send_command_atomic and add 5th parameter to inform if called from an atomic context. Call inside usleep_range (if non-atomic) or udelay (if atomic). 2. Change i40e_asq_send_command to invoke i40e_asq_send_command_atomic(..., false). 3. Change two functions: - i40e_aq_set_vsi_uc_promisc_on_vlan - i40e_aq_set_vsi_mc_promisc_on_vlan to explicitly use i40e_asq_send_command_atomic(..., true) instead of i40e_asq_send_command, as they use spinlocks and do some work in an atomic context. All other calls to i40e_asq_send_command remain unchanged.
