From 4c5406e2256a0a49bfe0373bad33d1b9dd698c45 Mon Sep 17 00:00:00 2001 From: liangchaozhong Date: Mon, 14 Nov 2022 22:19:08 +0800 Subject: [PATCH] dhcpc:disable broadcast flag in DHCP process Issue: DHCP server will send DHCP offer/ack via broadcast packet if broadcast flag is enabled in DHCP discover/request. There's no retransmition mechanism for broadcast frame in 802.11 MAC layer, thus transmit fail rate might be very high. This will increase DHCP fail rate. Solution: Disable broadcast flag by default Signed-off-by: liangchaozhong --- netutils/dhcpc/Kconfig | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/netutils/dhcpc/Kconfig b/netutils/dhcpc/Kconfig index 49e55856c..2862e0ce7 100644 --- a/netutils/dhcpc/Kconfig +++ b/netutils/dhcpc/Kconfig @@ -32,7 +32,7 @@ config NETUTILS_DHCPC_RETRIES config NETUTILS_DHCPC_BOOTP_FLAGS hex "Flags of Bootstrap" - default 0x8000 + default 0x0000 ---help--- This setting to set the BOOTP broadcast flags.
