From: Vegard Nossum Date: Tue, 12 Oct 2021 09:34:46 +0000 (+0200) Subject: net: arc: select CRC32 X-Git-Tag: v4.4.290~31 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b35db59649ed2fe01bd16527ba348938a93a6953;p=thirdparty%2Fkernel%2Fstable.git net: arc: select CRC32 commit e599ee234ad4fdfe241d937bbabd96e0d8f9d868 upstream. Fix the following build/link error by adding a dependency on the CRC32 routines: ld: drivers/net/ethernet/arc/emac_main.o: in function `arc_emac_set_rx_mode': emac_main.c:(.text+0xb11): undefined reference to `crc32_le' The crc32_le() call comes through the ether_crc_le() call in arc_emac_set_rx_mode(). [v2: moved the select to ARC_EMAC_CORE; the Makefile is a bit confusing, but the error comes from emac_main.o, which is part of the arc_emac module, which in turn is enabled by CONFIG_ARC_EMAC_CORE. Note that arc_emac is different from emac_arc...] Fixes: 775dd682e2b0ec ("arc_emac: implement promiscuous mode and multicast filtering") Cc: Arnd Bergmann Signed-off-by: Vegard Nossum Link: https://lore.kernel.org/r/20211012093446.1575-1-vegard.nossum@oracle.com Signed-off-by: Jakub Kicinski Signed-off-by: Greg Kroah-Hartman --- diff --git a/drivers/net/ethernet/arc/Kconfig b/drivers/net/ethernet/arc/Kconfig index 52a6b16f57d20..6b5b4d2843d40 100644 --- a/drivers/net/ethernet/arc/Kconfig +++ b/drivers/net/ethernet/arc/Kconfig @@ -19,6 +19,7 @@ config ARC_EMAC_CORE tristate select MII select PHYLIB + select CRC32 config ARC_EMAC tristate "ARC EMAC support"
