Correction. The commit is:

345c66695569db83eed100723e4df72cb54df7de

I will try the revert and let you know.

strace shows the following - clear ENOMEM

socket(AF_PACKET, SOCK_RAW, 768) = 5
ioctl(5, SIOCGIFINDEX, {ifr_name="eth0", }) = 0
bind(5, {sa_family=AF_PACKET, proto=0x03, if2, pkttype=PACKET_HOST, addr(0)={0, }, 20) = 0
setsockopt(5, SOL_PACKET, PACKET_AUXDATA, [1], 4) = 0
setsockopt(5, SOL_SOCKET, SO_ATTACH_FILTER, "\v\0\0\0\0\0\0\0`\330\260\330\275U\0\0", 16) = -1 ENOMEM (Cannot allocate memory)
sendto(3, "<27>Oct 12 09:23:46 dhclient[278"..., 95, MSG_NOSIGNAL, NULL, 0) = 95
write(2, "Can't install packet filter prog"..., 59Can't install packet filter program: Cannot allocate memory) = 59
write(2, "\n", 1
) = 1
