net: cisco: Replace zero-length array with flexible-array member The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] Lastly, fix the following checkpatch warning: CHECK: Prefer kernel type 'u32' over 'u_int32_t' #61: FILE: drivers/net/ethernet/cisco/enic/vnic_devcmd.h:653: + u_int32_t val[]; This issue was found with the help of Coccinelle.

enic: fix UDP rss bits In commit 48398b6e7065 ("enic: set UDP rss flag") driver needed to set a single bit to enable UDP rss. This is changed to two bit. One for UDP IPv4 and other bit for UDP IPv6. The hardware which supports this is not released yet. When released, driver should set 2 bit to enable UDP rss for both IPv4 and IPv6. Also add spinlock around vnic_dev_capable_rss_hash_type().

enic: add devcmd2 devcmd is an interface for driver to communicate with fw/adaptor. It involves writing data to hardware registers and waiting for the result. This mechanism does not scale well. The queuing of "no wait" devcmds is done in firmware memory rather than on the host. Firmware memory is a rather more scarce and valuable resource than host memory. A devcmd storm from one vf can disrupt the service on other pf/vf. The lack of flow control allows for possible denial of server from one VM to another. Devcmd2 uses work queue to post the devcmds, just like tx work queue. This allows better flow control. Initialize devcmd2, if fails we fall back to devcmd1. Also change the driver version.
