Almost everything seems to be in order. Almost - since you don't get
link... I don't think I have tried using this kind of Direct Attach
Cable - so maybe it just needs some more time. Let's see if the
following makes any difference (other than delay the failure for another
2.7 seconds):
diff --git a/drivers/net/bnx2x_link.c b/drivers/net/bnx2x_link.c
index ff70be8..bcee38c 100644
--- a/drivers/net/bnx2x_link.c
+++ b/drivers/net/bnx2x_link.c
@@ -3113,7 +3113,7 @@ static u8
bnx2x_wait_for_sfp_module_initialized(struct link_params *params)
u16 timeout;
/* Initialization time after hot-plug may take up to 300ms for
some
phys type ( e.g. JDSU ) */
- for (timeout = 0; timeout < 60; timeout++) {

if (bnx2x_read_sfp_module_eeprom(params, 1, 1, &val)
== 0) {
DP(NETIF_MSG_LINK, "SFP+ module initialization "
If it does help, be sure to let me know how much time it took (you
should have this debug print).
