2020-05-13{IB/net}/mlx5: Simplify don't trap codeMaor Gottlieb2-70/+56
The fs_core already supports creation of rules with multiple actions/destinations. Refactor fs_core to handle the case when don't trap rule is created with destination. Adapt the calling code in the driver.

2020-05-11net/mlx5: Replace zero-length array with flexible-arrayGustavo A. R. Silva3-35/+35
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] sizeof(flexible-array-member) triggers a warning because flexible array members have incomplete type[1]. There are some instances of code in which the sizeof operator is being incorrectly/erroneously applied to zero-length arrays and the result is zero. Such instances may be hiding some bugs. So, this work (flexible-array member conversions) will also help to get completely rid of those sorts of issues. This issue was found with the help of Coccinelle.

2020-05-01net/mlx5: Change lag mutex lock to spin lockMaor Gottlieb1-21/+21
The lag lock could be a spin lock, the critical section is short and there is no need that the thread will sleep. Change the lock that protects the LAG structure from mutex to spin lock. It is required for next patch that need to access this structure from context that we can't sleep. In addition there is no need to hold this lock when query the congestion counters.
