What is the standard way of looping through the lower dimension of a multidimensional array? With the higher dimension fixed.
In the following example:
automatic int i = 2;
foreach (my_req[i][j]) begin // <-- WARNING
$display("i:%0d,j:%0d", i, j);
end
I see the warning:
** Warning: testbench.sv(16): (vlog-LRM-2897) Using non-standard foreach loop variable list syntax.

You can do this:
$display("Loop through i=2");
begin
automatic int i = 2;
foreach (my_req[,j]) begin // notice the "," before j
$display("i:%0d,j:%0d", i, j);
end
end
Working code on EDA Playground:
The warning is to let you know that the code you are writing may not be compatible with other simulators.
I do know that at one time, another simulator accepted foreach (array[i][j]) where i was not previously defined to mean the same thing as foreach(array[i,j]), and that syntax would not be compatible with what you are trying to do.
The correct syntax is foreach (my_req[,j])
