does anybody have an idea to fix this problem ?

Which paramter is for the "lan connection timeout" ?

Try to decrease CFG_MACB_AUTONEG_TIMEOUT in drivers/net/macb.c to 500000 or so. It is currently 5000000 which results in 5 sec. timeout in macb_phy_init() and also in macb_phy_reset().

Caution: don't reduce it to less than 2 seconds. The minimum PHY autonegotiation time is 2 seconds per definition by the standard: if you read the standard and add all the delays together, the sum is 2 seconds.

I've never seen a PHY take noticeably longer than 2 seconds for autonegotiation, but there is a world of PHYs out there that I've never tried.
