Subject[PATCH net V2] net: stmmac: Premature loop termination check was ignored
Date

The premature loop termination check makes sense only in case of the
jump to read_again where the count may have been updated. But
read_again did not include the check.

Fixes: bba2556efad6 (net: stmmac: Enable RX via AF_XDP zero-copy)
Fixes: ec222003bd94 (net: stmmac: Prepare to add Split Header support)
Signed-off-by: Jochen Henneberg <jh@henneberg-systemdesign.com>

V2: Added fixes tags for both commits that introduced the issues
