Added the USB IDs 0x413c:0x81b1 for the Dell Wireless 5809e Gobi(TM) 4G
LTE Mobile Broadband Card, a Dell-branded Sierra Wireless EM7305 LTE
card in M.2 form factor, used eg. in Dell's Latitude E7540 Notebook
Patch for 4.1.1.
Essentially all that is needed to get rid of this issue is the
addition of:
memset(u, 0, sizeof(*u));
after:
if (!(u = malloc(sizeof(*u
break;
Also patched some other situations (strcpy and sprintf uses) that
potentially produce the same results.
With commit c03abd84634d (net: ethernet: cpsw: don't requests IRQs

Hello,
This serie adds support for more instructions to the ARM BPF JIT
namely skb netdevice type retrieval, skb payload offset retrieval, and
skb packet type retrieval.
This allows 35 tests to use the JIT instead of 29 before.
This serie depends on the BPF JIT fixes for ARM serie sent earlier.
Utilize the new metadata dst to attach encapsulation instructions to
the skb. The existing egress_tun_info via the OVS_CB() is left in
place until all tunnel vports have been converted to the new method.
